The moss Physcomitrella patens contains high levels of arachidonic acid and lesser amounts of eicosapentaenoic acid. Here we report the identification and characterization of a delta5-desaturase from P. patens that is associated with the synthesis of these fatty acids. A full-length cDNA for this desaturase was identified by data base searches based on homology to sequences of known delta5-desa...

In this study, total lipid and fatty acid profiles of Barbus tauricus samples which were obtained from Melen River Basin during winter, spring, summer seasons, evaluated. Total levels determined 2.27%, 2.37%, 4.34% in summer, respectively. The study also that the carbon count 30 acids, composing fat compositions B. caught Basin, ranges among 12-24. major acids are palmitic stearic SFA; palmitol...

Abstract In this study, the effects of different feeds on fatty acid composition in Chinese mitten crab ( Eriocheir sinensis ) were investigated. The was significantly correlated with type feed source provided. Differences between groups pertained mainly five acids: oleic acid, linoleic palmitic eicosapentaenoic (EPA) and docosahexaenoic (DHA). content EPA DHA higher group frozen trash fish tha...

Infusion of fish oil-based (n-3) lipids may influence leukocyte function and plasma lipids in critical care patients. Twenty-one patients with sepsis requiring parenteral nutrition were randomized to receive an n-3 lipid emulsion rich in eicosapentaenoic acid and docosahexaenoic acid or a conventional (n-6) lipid emulsion (index fatty acid: arachidonic acid) for 5 days. The impact on plasma-fre...

The incorporation of the fatty acids in fish and olive oil into the colonic mucosa of patients with inflammatory bowel disease was examined during 12 weeks' dietary supplementation with the oils, and the influence on colonic mucosal prostaglandin and thromboxane generation was measured. With a dietary supplement of 18 g fish oil daily, concentrations of the major polyunsaturated fatty acids in ...

Microalgae oil serves as a feedstock for a biorefinery approach to mid-chain (di-)carboxylic acid esters, currently only accessible via demanding synthetic routes. Via the butenolysis of monoand poly-unsaturated fatty acids, short-chain unsaturated fatty acid methyl esters and monoand di-enes were produced in a high selectivity. These olefins were further processed into value added linear mid-c...
