Cyclohexyl hexadecanoate, hexadecyl propionate, and N-(3-hydroxypropionyl)pentadecanamide, resp. ester, retroester, and retroamide derivatives of N-palmitoylethanolamine, represent the first selective inhibitors of “N-palmitoylethanolamine hydrolase” described so far. These compounds are devoid of affinity for CB₁ and CB₂ receptors and characterized by high percentages of inhibition of N-palmitoylethanolamine-selective acid amidase (84.0, 70.5, and 76.7% inhibition at 100 μM, resp.) with much lower inhibitory effect on either fatty acid amide hydrolase or the uptake of anandamide.

Koike, Kenzo published the artcileSubstrate specificity of regiospecific desaturation of aliphatic compounds by a mutant Rhodococcus strain, Recommanded Product: Isobutyl palmitate, the publication is Bioscience, Biotechnology, and Biochemistry (2000), 64(5), 1064-1066, database is CAplus and MEDLINE.

Substrate specificity of cis-desaturation of aliphatic compounds by resting cells of a mutant, Rhodococcus sp. strain KSM-MT66, was examined Among substrates tested, the rhodococcal cells were able to convert n-alkanes (C13-C19), 1-chloroalkanes (C16 and C18), Et fatty acids (C14-C17) and alkyl (C1-C4) esters of palmitic acid to their corresponding unsaturated products of cis configuration. The products from n-alkanes and 1-chloroalkanes had a double bond mainly at the 9th carbon from their terminal Me groups, and the products from acyl fatty acids had a double bond mainly at the 6th carbon from their carbonyl carbons.

Knothe, Gerhard published the artcileKinematic viscosity of biodiesel fuel components and related compounds. Influence of compound structure and comparison to petrodiesel fuel components, Application In Synthesis of 110-34-9, the publication is Fuel (2005), 84(9), 1059-1065, database is CAplus.

Biodiesel, defined as the mono-alkyl esters of vegetable oils and animal fats is an alternative diesel fuel that is steadily gaining attention and significance. One of the most important fuel properties of biodiesel and conventional diesel fuel derived from petroleum is viscosity, which is also an important property of lubricants. Ranges of acceptable kinematic viscosity are specified in various biodiesel and petrodiesel standards In this work, the kinematic viscosity of numerous fatty compounds as well as components of petrodiesel were determined at 40 °C (ASTM D445) as this is the temperature prescribed in biodiesel and petrodiesel standards The objective is to obtain a database on kinematic viscosity under identical conditions that can be used to define the influence of compound structure on kinematic viscosity. Kinematic viscosity increases with chain length of either the fatty acid or alc. moiety in a fatty ester or in an aliphatic hydrocarbon. The increase in kinematic viscosity over a certain number of carbons is smaller in aliphatic hydrocarbons than in fatty compounds The kinematic viscosity of unsaturated fatty compounds strongly depends on the nature and number of double bonds with double bond position affecting viscosity less. Terminal double bonds in aliphatic hydrocarbons have a comparatively small viscosity-reducing effect. Branching in the alc. moiety does not significantly affect viscosity compared to straight-chain analogs. Free fatty acids or compounds with hydroxy groups possess significantly higher viscosity. The viscosity range of fatty compounds is greater than that of various hydrocarbons comprising petrodiesel. The effect of dibenzothiophene, a sulfur-containing compound found in petrodiesel fuel, on viscosity of toluene is less than that of fatty esters or long-chain aliphatic hydrocarbons. To further assess the influence of the nature of oxygenated moieties on kinematic viscosity, compounds with 10 carbons and varying oxygenated moieties were investigated. A reversal in the effect on viscosity of the carboxylic acid moiety vs. the alc. moiety is noted for the C10 compounds compared to unsaturated C18 compounds Overall, the sequence of influence on kinematic viscosity of oxygenated moieties is COOH≈C-OH>COOCH₃≈C=O>C-O-C> no oxygen.

Fan, Chunying published the artcileChemical compositions and copper(II) adsorption properties of sequentially extracted humic substances, including different humin fractions, Recommanded Product: Isobutyl palmitate, the publication is Fresenius Environmental Bulletin (2018), 27(10), 6485-6499, database is CAplus.

Humin (HU) is the least understood humic substance (HS) fractions due to its close associations with soil mineral colloids. Here, humic acid (HA), fulvic acid (FA), HU, iron-bound HU (HUi), claybound HU (HUc) and residual HU (HUr) were sequentially extracted from an Alfisol of northeast China. Elemental anal., solid-state carbon-13 cross-polarization magic-angle-spinning NMR (13C CPMAS NMR) spectroscopy and pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS) were used to characterize HS fractions. The adsorption isotherms of Cu(II) on HS fractions were obtained using batch equilibrium method. Among these HS fractions, HA contained higher proportion of phenols, whereas HUc exhibited higher proportion of aliphatic hydrocarbons. For the different HU fractions, n-alkanes/n-alkenes were particularly abundant in HUc, whereas polysaccharides were abundant in HUr. The adsorption of Cu(II) on HS fractions well fitted both Freundlich and Langmuir equations. The maximum amounts of Cu(II) adsorbed was FA > HUi > HA > HUc > HU > HUr, which was pos. correlated with their O/C ratio and carbonyl C whereas neg. correlated with C/N ratio (p < 0.01). The results suggested that HU is highly heterogeneous in terms of their chem. compositions and plays important role in controlling the behavior and fate of Cu(II) in the environment.

Milovanovic, Dusan published the artcileRisk assessment approach for prioritizing danube basin-specific pollutants: a case study in the novi sad region, Recommanded Product: Isobutyl palmitate, the publication is Polish Journal of Environmental Studies (2019), 28(6), 4297-4309, database is CAplus.

The aim of this work was to determine the most relevant pollutants in Danube surface water and wastewater in the city of Novi Sad, and to conduct a risk assessment approach on substances for the optimization of future monitoring programs. According to the requirements of Serbian law, obligatory and operating monitoring was focused on physico-chem. and biol. parameters while the expanded monitoring programs have not been applied – often due to practical circumstances. Novi Sad, with a population of more than 300.000 inhabitants, does not have a wastewater treatment plant, and about 2 m3 of wastewater is discharged directly to the Danube river every day. Screening analyses of the water within the Danube basin around city of Novi Sad included more than 300 different organic substances, while target anal. was conducted for all WFD pollutants. The methodol. for generating the list of priority substances was applied for the first time in the Danubian region around the city of Novi Sad. By applying the prioritization procedure, 86 organic substances were determined in screening analyses and 27 substances obtained within target analyses were identified as the most relevant. In addition, seasonal variation anal. was conducted to determine the occurrence trends of specific compounds in different seasons.

GC-MS using both electron impact and chem. ionization detection modes led to the determination of the volatile composition of 2 samples of freshly distilled Cognac and 2 samples of freshly distilled Calvados. A total of 169 volatile compounds were directly identified in dichloromethane extracts obtained by liquid-liquid extraction Trace compounds present in both spirits were characterized with the help of preparative separations In a 1st step, groups of compounds were separated by preparative GC, and the fractions were analyzed on a polar stationary phase by GC-MS. In a 2nd step, silica gel fractionation was used to sep. them by polarity. In 331 compounds, of which 162 can be considered as trace compounds, were characterized in both freshly distilled Cognac and Calvados. Of these, 39 are common to both spirits; 30 are specific to Cognac with numerous hexenyl esters and norisoprenoidic derivatives, whereas 93 are specific to Calvados with compounds such as unsaturated alcs., phenolic derivatives, and unsaturated aldehydes.
