Rice rhizodeposition plays an important role in carbon sequestration in paddy soils. However, the pathways through which rice rhizodeposits contribute to soil organic C (SOC) formation are poorly understood because of specific paddy soil conditions. Furthermore, microbial necromass has been largely ignored in studies examining the contribution of rhizodeposits to C sequestration during plant growth. To evaluate the contribution of microbial necromass to SOC formation via rhizodeposition, rice (Oryza sativa L.) plants were continuously labeled with ¹³CO₂ for 38 days under ambient (aCO₂, 400渭L L^-1) or elevated CO₂ (eCO₂, 800渭L L^-1) in a paddy field at two levels of N fertilization. The distributions of photosynthetic-¹³C in the shoots and roots, microbial communities, and SOC fractions were quantified. eCO₂ increased plant growth and, consequently, the total ¹³C incorporated into the shoots, roots, and SOC compared to aCO₂, while N fertilization (100 kg N ha^-1) decreased root biomass and rhizodeposits in the soil and microbial pools, including living biomass (phospholipid fatty acids, PLFA) and microbial necromass (amino sugars). Rhizodeposits were initially immobilized mainly by bacteria and preferentially recovered in fungal necromass (glucosamine). While ¹³C incorporation into PLFAs was slightly increased during plant growth, ¹³C in microbial necromass increased greatly between the tillering and booting stages. Fungal necromass, which is less decomposable compared to bacterial residues, was the largest contributor to C sequestration with rhizodeposits via the mineral-associated SOC fraction, particularly under elevated CO₂ without N fertilization. This study reveals the significance of the C pathways from rhizodeposits through fungal necromass and organo-mineral associations for the build up of SOC in paddy fields. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Name: Methyl nonadecanoate).

Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Name: Methyl nonadecanoate

Investigation of therapeutic effect of curcumin 伪 and 尾 glucoside anomers against Alzheimer’s disease by the nose to brain drug delivery was written by Ahmadi, Nahid;Hosseini, Mir-Jamal;Rostamizadeh, Kobra;Anoush, Mahdieh. And the article was included in Brain Research in 2021.Reference of 604-69-3 The following contents are mentioned in the article:

Alzheimer’s disease (AD) is one of the greatest geriatric medicinal challenges of our century and is the main disease leading to dementia. Despite extensive scientific research advances, available disease-modifying treatment strategies remained limited; thus, increasing demand for new drugs. In recent years, medicinal plants attracted attention due to their potential role in dementia. In the present study, 伪 and 尾 anomers of curcumin glucosides (CGs) were synthesized and evaluated for Alzheimer’s treatment. CGs were synthesized by fusion reaction as a novel and easy method with more advantages (high yield, short reaction time, and low chems.), and the products were characterized using HNMR. Wistar male rats were used to administer different treatments. They divided into control, sham, Alzheimer, and test groups (Alzheimer + 伪 anomer and Alzheimer + 尾 anomer). Animals received normal saline, Scopolamine (1 mg/kg), high dose anomers, scopolamine, and two doses (12.5 and 25 mg/kg) of anomers, resp., for 10 days. Then the Morris Water Maze (MWM) test was performed on all animals. Finally, the animals’ brains were extracted and homogenized for glutathione, acetylcholine esterase activity, protein carbonyl, and lipid peroxide level detection. The escape latency and the distance towards the hidden platform in Morris water maze in the Alzheimer group were significantly higher than both the control and test groups. Besides, there were no significant differences between sham and control groups in all tests. Both anomers led to a significant increase in glutathione, and acetylcholine levels while they caused a decrease in lipid peroxidation and protein carbonyl levels in brain tissue. It seems that intranasal administration of both anomers pos. influenced maze learning in scopolamine receiving subjects. Although both anomers resulted in similar biochem. tests, a higher dose of 尾 anomer indicated better results than 伪 anomer not only in behavioral tests but also in biochem. tests. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Reference of 604-69-3).

(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product.

Stress response to oxytetracycline and microplastic-polyethylene in wheat (Triticum aestivum L.) during seed germination and seedling growth stages was written by Bao, Yanyu;Pan, Chengrong;Li, Dezheng;Guo, Aiyun;Dai, Fengbin. And the article was included in Science of the Total Environment in 2022.Computed Properties of C21H44O5 The following contents are mentioned in the article:

Much efforts have been devoted to clarify the phytotoxicity of individual contaminants in plants, such as individual antibiotic and microplastic; however, little is known about the phytotoxicity of their combined exposure. Here, we investigated the effects of individual and combined exposure of wheat (Triticum aestivum L.) (Xiaoyan 22) to oxytetracycline (OTC) and polyethylene (PE) microplastics using physiol. and metabolic profilings. During the seed germination stage, OTC induced phytotoxicity, as observed through the changes of root elongation, sprout length, fresh weight and the vitality index, with significant effect at the 50 and 150 mg路L-1 levels; the effect of PE microplastics depended on the OTC level in the combined exposure groups. During seedling cultivation, catalase (CAT) and ascorbate peroxidase (APX), as antioxidant enzyme indexes, were sensitive to OTC exposure stress, although OTC was not determined in leaves. Untargeted metabolomics of wheat leaves revealed OTC concentration-, metabolite class- and PE-dependent metabolic responses. Dominant metabolites included carboxylic acids, alcs., and amines in the control group and all treatment groups. Compared to only OTC treatment, PE reprogrammed carboxylic acid and alc. profiles in combined exposure groups with obvious separation in PLS-DA. Combined exposure induced fewer metabolites than OTC exposure alone at the 5 and 50 mg路L-1 levels. The shared metabolite numbers were higher in the OTC groups than in the PE-OTC groups. Pathway enrichment anal. showed a drift in metabolic pathways between individual and combined exposure to OTC and PE, which included glyoxylate and dicarboxylate metabolism, amino acid metabolism and isoquinoline alkaloid biosynthesis. Among metabolites, aromatic acids and amino acids were more sensitive to combined exposure than individual exposure. These results contribute to clarifying the underlying mechanisms of phytotoxicity of individual and combined exposure to OTC and PE. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Computed Properties of C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C21H44O5

tert-Butyl esters of aliphatic dibasic acids was written by Backer, H. J.;Homan, J. D. H.. And the article was included in Recueil des Travaux Chimiques des Pays-Bas et de la Belgique in 1939.Name: Di-tert-butyl decanedioate The following contents are mentioned in the article:

Di-tert-Bu esters (I) of aliphatic dibasic acids with an even number of C atoms (up to sebacic) have higher m. ps. than the neighboring odd-numbered acids. I also have higher m. ps. than the corresponding Me and Et esters with the single exception of MeO₂C(CH₂)₈CO₂Me. The striking oscillation in the m. ps. of I is apparent in the following series of m. ps. of the esters from the oxalate (II) to the sebacate (III) resp.: 71掳, -7掳, 36掳, -10掳, 32.5掳, -15掳, 29掳, -18掳, 18掳. Two general methods were followed in the preparation of the esters, the 1st, using C₅H₅N as catalyst, the 2nd Me₂NPh (IV). The acid chlorides (0.2 mol.) in 2 volumes of anhydrous C₆H₆ are added dropwise to 1 mol. Me₃COH (V) (dried over Na) in 0.6 mol. C₅H₅N (distilled over KOH). The reaction mixture is agitated and maintained below 50掳. Upon completion of the 1st stage the solution is heated in a water bath for 3 hrs., cooled and the precipitate filtered and washed with C₆H₆. The filtrate is made acidic to Congo red and the 2 layers formed are separated The H₂O layer is extracted thrice with C₆H₆ and the combined C₆H₆ solutions are washed successively with 2.0 N H₂SO₄ and Na₂CO₃ solution, then dried over anhydrous Na₂SO₄ with a little fused K₂CO₃. The C₆H₆ is removed in vacuo and the products (except II) are likewise distilled in vacuo. When IV is used as catalyst CHCl₃ (dried over CaCl₂) is used as solvent and extractions are made with petr. ether. The following di-tert-Bu esters were prepared: II (87% yield); malonate, b₁₀ 93掳 (78% yield); succinate, b₁₄ 115掳 (31%); glutarate, b₁₃ 125.5掳; adipate, b₁₀ 134掳 (60%); pimelate, b₁₁ 174掳 (60%); suberate, b₁₁ 160掳 (64%); azelate, b₁₃ 174掳 (70%); sebacate, b₁₃ 185掳 (74%). Several mixed ester-salts were prepared by saponification 1 of the acid radicals with alc. KOH. This study involved multiple reactions and reactants, such as Di-tert-butyl decanedioate (cas: 143050-66-2Name: Di-tert-butyl decanedioate).

Di-tert-butyl decanedioate (cas: 143050-66-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Di-tert-butyl decanedioate

A package of established analytical tools to investigate the solid-state alteration of lipid-based excipients was written by Salar-Behzadi, Sharareh;Corzo, Carolina;Laggner, Peter. And the article was included in Journal of Visualized Experiments in 2022.Safety of Glyceryl monostearate The following contents are mentioned in the article:

Lipid-based excipients (LBEs) are low-toxic, biocompatible, and natural-based, and their application supports the sustainability of pharmaceutical manufacturing However, the major challenge is their unstable solid-state, affecting the stability of the pharmaceutical product. Critical phys. properties of lipids for their processing-such as melt temperature and viscosity, rheol., etc.-are related to their mol. structure and their crystallinity. Additives, as well as thermal and mech. stress involved in the manufacturing process, affect the solid-state of lipids and thus the performance of pharmaceutical products thereof. Therefore, understanding the alteration in the solid-state is crucial. In this work, the combination of powder x-ray diffraction and differential scanning calorimetry (DSC) is introduced as the gold standard for the characterization of lipids’ solid state. X-ray diffraction is the most efficient method to screen polymorphism and crystal growth. The polymorphic arrangement and the lamella length are characterized in the wide- and small-angle regions of x-ray diffraction, resp. The small-angle x-ray scattering (SAXS) region can be further used to investigate crystal growth. Phase transition and separation can be indicated. DSC is used to screen the thermal behavior of lipids, estimate the miscibility of additives and/or active pharmaceutical ingredients (API) in the lipid matrix, and provide phase diagrams. Four case studies are presented in which LBEs are either used as a coating material or as an encapsulation matrix to provide lipid-coated multiparticulate systems and lipid nanosuspensions, resp. The lipid solid-state and its potential alteration during storage are investigated and correlated to the alteration in the API release. Qual. microscopical methods such as polarized light microscopy and SEM are complementary tools to investigate micro-level crystallization Further anal. methods should be added based on the selected manufacturing process. The structure-function-processability relationship should be understood carefully to design robust and stable lipid-based pharmaceutical products. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Safety of Glyceryl monostearate).

Short communication: Technological and seasonal variations of vitamin D and other nutritional components in donkey milk was written by Martini, Mina;Altomonte, Iolanda;Licitra, Rosario;Salari, Federica. And the article was included in Journal of Dairy Science in 2018.Recommanded Product: Methyl nonadecanoate The following contents are mentioned in the article:

Vitamin D is an essential nutrient that plays a crucial role in calcium homeostasis and bone metabolism and also acts as a hormone. Although several studies on the content of vitamin D in bovine milk have been conducted, little information is available regarding donkey milk. In the context of the nutritional assessment of donkey milk, the aim of this study was to assess the vitamin D content in donkey milk and its chem. profile, with particular reference to seasonal and technol. modifications after pasteurization. The study was conducted on a dairy farm that produces donkey milk for human consumption located in central Italy. At sampling time, an aliquot of total bulk milk production was sampled before and after pasteurization (63掳C for 30 min without homogenization) with a total of 20 raw and 20 pasteurized milk samples. The samples were collected for 10 mo, every 15 d, from May to Feb. 2017. All the samples were analyzed for the chem. composition and vitamin D₂ and D₃ content by HPLC after saponification The donkey milk analyzed showed a higher average vitamin D content (raw milk: vitamin D₂ = 1.68, vitamin D₃ = 0.60 渭g/100 mL; pasteurized milk: vitamin D₂ = 1.38, vitamin D₃ = 0.30 渭g/100 mL) than reported for bovine and human milk. The results of the effect of pasteurization on milk did not highlight significant differences in the total content of vitamin D. However, vitamin D₃ has a poor thermal stability, which led to a significant reduction in content in pasteurized milk compared with raw milk. The total vitamin D content of donkey milk did not show significant variations between seasons; however, a higher concentration of vitamin D₃ was found in spring and summer. In conclusion, raw and pasteurized donkey milk showed a high content of vitamin D, which could be useful in meeting the deficiencies of this vitamin in humans. Further investigations are needed to improve the vitamin D content in donkey milk by increasing its endogenous synthesis or its transfer in milk and to clarify other variability factors. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Recommanded Product: Methyl nonadecanoate).

Digestion of lipid excipients and lipid-based nanocarriers by pancreatic lipase and pancreatin was written by Zoeller, Katrin;To, Dennis;Knoll, Patrick;Bernkop-Schnuerch, Andreas. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2022.Reference of 31566-31-1 The following contents are mentioned in the article:

The digestion behavior of lipid-based nanocarriers (LNC) has a great impact on their oral drug delivery properties. In this study, various excipients including surfactants, glycerides and waxes, as well as various drug-delivery systems, namely self-emulsifying drug delivery systems (SEDDS), solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) were examined via the pH-stat lipolysis model. Lipolysis experiments with lipase and pancreatin revealed the highest release of fatty acids for medium chain glycerides, followed by long chain glycerides and surfactants. Waxes appeared to be poor substrates with a maximum digestion of up to 10% within 60 min. Within the group of surfactants, the enzymic cleavage decreased in the following order: glycerol monostearate > polyoxyethylene (20) sorbitan monostearate > PEG-35 castor oil > sorbitan monostearate. After digestion experiments of the excipients, SEDDS, SLN and NLC with sizes between 30 and 300 nm were prepared The size of almost all formulations was increasing during lipolysis and levelled off after approx. 15 min except for the SLN and NLC consisting of cetyl palmitate. SEDDS exceeded 6000 nm after some minutes and were almost completely hydrolyzed by pancreatin. No significant difference was observed between comparable SLN and NLC but surfactant choice and selection of the lipid component had an impact on digestion. SLN and NLC with cetyl palmitate were only digested by 5% whereas particles with glyceryl distearate were decomposed by 40-80% within 60 min. Addnl., the digestion of the same SLN or NLC, only differing in the surfactant, was higher for SLN/NLC containing polyoxyethylene (20) sorbitan monostearate than PEG-35 castor oil. This observation might be explained by the higher PEG content of PEG-35 castor oil causing a more pronounced steric hindrance for the access of lipase. Generally, digestion experiments performed with pancreatin resulted in a higher digestion compared to lipase. According to these results, the digestion behavior of LNC depends on both, the type of nanocarrier and on the excipients used for them. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Effects of oven and foam mat drying on proximate, functional, and reconstitution characteristics of instant powders from selected legumes was written by Falade, Kolawole O.;Adedeji, Alice O.. And the article was included in Journal of Food Processing and Preservation in 2022.Application In Synthesis of Glyceryl monostearate The following contents are mentioned in the article:

The effects of oven and foam mat drying on proximate, functional, and reconstitution characteristics of instant powders from selected legumes were investigated. Cotyledons of the legumes were sep. cooked and oven-dried, and sep. cooked and foamed, using glyceryl monostearate and egg albumin, and oven-dried. Foam d. of pastes incorporated with egg albumin or glyceryl monostearate (3-6 min) varied with whipping time and legume. Dry matter, protein, ash, crude fiber, fat and carbohydrate contents of oven- and foam-mat-dried legume powders varied from 92.75-98.75, 20.05-51.68, 0.96-1.07, 0.60-3.87, 1.36-4.13, and 43.63-71.85 g/100 g. Loose and packed bulk densities ranged from 0.48-0.63 to 0.68-0.9 g/mL, while WAC and OAC varied from 3.01-3.99 to 2.04-2.67 g/g, resp. Dispersability, wettability, solubility, and swelling index varied from 6.33-216.00, 6.33-216.00, 6.67-46.01 s, and 2.54-6.67 g/g, resp. The oven- and foam-mat-dried powders could provide the basis for preparation of acceptable instant soups from the selected legumes. Legumes are cheap and good source of essential protein and other nutrients with great nutritional benefits. However, legumes have minimal utilization due to associated prolonged and difficulty of cooking, and low palatability. Moreover, the processing of legumes into soups is laborious, time-consuming, and energy intensive, particularly when the product is needed to be produced frequently. Conversion of underutilized legumes to instant soup-based powders to which other ingredients could be added for the preparation of soups has huge potentials. This will allow for the preparation of soups with different variety, taste, and consistency based on consumers preference. Therefore, processing of underutilized legumes into instant soup-base powders which could be reconstituted and prepared present an innovative way of improving legume utilization and alleviate associated challenges. Dehydration of cooked legume cotyledon or pastes into instant powder would further enhance the shelf stability and reconstitution of the instant soup-base powders. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Application In Synthesis of Glyceryl monostearate).

In recent years, there has been a progressive gradual development in the use of medicinal plants in developing nations, owing to the fact those herbal medicines are safe and have few side effects, especially when compared to synthetic pharmaceuticals. As the occurrence of unwanted side effects appears to be less common with herbal medications compared to allopathic treatments, the usage of herbal drugs is increasing, resulting in a rapid increase in the number of herbal drug makers. Since they are typically less expensive than synthetic medications People have been increasingly using herbal medicines during the last few decades. The present study was commenced to evaluate the quant. profiling and antimicrobial activity of cream prepared from extracts of traditional plants like Kanthkari, Rasana, and Nirgundi. In the present study, a cream was formulated which comprised of an extract of plant materials. The dried plant materials of Kanthkari, Rasana, and Nirgundi were individually extracted using the maceration method. These three different types of extracts were used for the preparation of cream and evaluated for the HPTLC profiling and antimicrobial activity. The HPTLC profiling of the extract and formulation was performed on pre-coated silica gel Aluminum Plate 60F-254 using Toluene: Ethylacetate: FormicAcid (8:1.5:0.5vol./volume/v) as mobile phase and a further quantity of Quercetin was evaluated in extract and formulation. The antimicrobial activity of prepared cream was evaluated against Escherichia coli and Staphylococcus aureus by disk diffusion method using reference disk of antibiotics. The result of antimicrobial the activity was determined by comparing the results of the zone of inhibition of formulation and solvent extract The formulation showed significant activity against the tested bacterial pathogens. The disk diffusion method was used to assess the antibacterial activity of methanolic extract using a reference disk of antibiotics. The Rf value and spectral scanning of standard Quercetin (Rf 0.22) match with the values of extract and formulation indicate the presence of Quercetin in extract and formulation.

Surface Activity of Alkoxy Ethoxyethyl 尾-D-Glucopyranosides was written by Fan, Yulin;Fu, Fang;Chen, Langqiu;Li, Jiping;Zhang, Jing. And the article was included in Journal of Agricultural and Food Chemistry in 2020.COA of Formula: C16H22O11 The following contents are mentioned in the article:

Dioxyethene fragment (-(OCH₂CH₂)₂-) was introduced into traditional alkyl 尾-D-glucopyranosides to ameliorate the water solubility, and eight nonionic surfactants, i.e., alkoxy ethoxyethyl 尾-D-glucopyranosides with alkyl chain lengths (n = 6-16), were synthesized and characterized. Their hydrophilic and lipophilic balance number, water solubility, critical micelle concentration (cmc), 纬_cmc, 螕_max, and hygroscopic rate decreased with an increase in the alkyl chain length. Hexadecoxy ethoxyethyl 尾-D-glucopyranoside had no water solubility at 25掳C. Decoxy ethoxyethyl 尾-D-glucopyranoside had the best emulsifying property in the toluene/water and n-octane/water systems and the strongest foaming property, whereas dodecoxy ethoxyethyl 尾-D-glucopyranoside had the best emulsifying property in the rapeseed oil/water system. Such 尾-D-glucopyranosides (n = 6-12) exhibited excellent surface activity. In addition, for the binary mixture of alkoxy ethoxyethyl 尾-D-glucopyranosides (n = 8, 10, 12) and sodium dodecyl sulfate or cetyl tri-Me ammonium chloride, their cmc values were lower than the pure 尾-D-glucopyranosides, indicating that they had synergistic interactions. The fan focal conic textures of alkoxy ethoxyethyl 尾-D-glucopyranosides (n = 7-16) were observed during the cooling process under a polarizing optical microscope. Alkoxy ethoxyethyl 尾-D-glucopyranosides (n = 14, 16) had the related m.ps. and the clear points with differential scanning calorimetry. With 尾-D-glucopyranosides (n = 6-16) and n-butanol as the surfactant and cosurfactant, resp., and with cyclohexane as the oil phase, the related microemulsion areas in their pseudoternary phase diagram system were investigated with the visual observation at 25掳C. Along with the slashing requirements of petroleum consumption, environmental protection, and green and sustainable development, nonionic sugar-based alkoxy ethoxyethyl 尾-D-glucopyranosides should be expected to have their potential practical application because of their strengthened hydrophilicity, improved water solubility, and enhanced surface activity.
