Fatty acids analysis in Hypomesus olidus different parts by GC-MS was written by Chen, Ping;Wang, Jian-gang;Zhang, Li. And the article was included in Shipin Gongye (Shanghai, China) in 2014.Formula: C20H40O2 The following contents are mentioned in the article:
The research aimed to determine and analyze the fatty acid compositions of Hypomesus olidus different parts. The lip soluble components were extracted from Hypomesus olidus different parts by Soxhlet extraction resp. The extracted fatty acids were identified by gas chromatog.-mass spectrometry (GC-MS) after Me etherification treatment, and the relative percentage of each component was confirmed by peak-area normalization method. The test results show that, the fat content in different parts of Hypomesus olidus was obviously different, the head (37.25%), muscle (29.87%) and visceral (67.58%). The fatty acid compositions were similar in different parts of Hypomesus olidus, main components of unsaturated fatty acids were palmitoleic acid, 9-octadecenoic acid, all z, 5,8,11,14,17-eicosapentaenoic acid, 4,7,10,13,16,19-docosahexaenoic acid, etc; the main components of saturated fatty acids were palmitic acid, tetradecanoic acid, octadecanoic acid, etc. The distribution of fatty acid contents has the obvious difference in different parts, EPA and DHA content in the visceral was significantly higher than that in other parts. This result provides the nutrition and health value of Hypomesus olidus was higher and it had comprehensive development and utilization prospect. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Formula: C20H40O2).
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, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C20H40O2
