Conjugated Linoleic Acid (CLA), Glycerol (G) and sunflower oil blends with varying concentration were subjected to enzymatic esterification using a 1, 3- specific immobilized lipase. CLA was used as acyl due to its purported health benefits. The transesterified lipids were evaluated for free fatty acids (FFA) and composition of fatty acids by gas chromatography. Lipozyme RM IM is preferred for ...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

Assessment of free fatty acid (FFA) concentration and isotopic enrichment is useful for studies of FFA kinetics in vivo. A new procedure to recover the major FFA from plasma for concentration and isotopic enrichment measurements is described and validated. The procedure involves extraction of plasma lipids with hexane, methylation with iodomethane (CH(3)I) to form fatty acid methyl esters (FAME...

Lipoprotein lipase (LPL) releases fatty acids from triglyceride-rich lipoproteins for use in cellular metabolic reactions. How this hydrolysis, which occurs at the vascular endothelium, is regulated is poorly understood. A fatty acid feedback system has been proposed by which accumulation of fatty acids impedes LPL-catalyzed hydrolysis and dissociates the enzyme from its endothelial binding sit...

BACKGROUND Free fatty acid (FFA) metabolism can impact on metabolic conditions, such as obesity and nonalcoholic fatty liver disease (NAFLD). This work studied the increase in total FFA shown in NAFLD subjects to possibly characterize which fatty acids significantly accounted for the whole increase. METHODS 21 patients with NAFLD were selected according to specified criteria. The control grou...

traditional raw milk cheese is one of the most consuming cheeses in the world. kurdish cheese is a semi-firm, traditionally made in the east of iran. it is manufactured from raw sheep or cow milk and kept in goat’s skin bags during ripening period. as a result kurdish cheese is often more complex in different varieties of microorganisms, which whose organoleptic properties make it highly esteem...

Changes in the release and esterification of free fatty acids (FFA) in adipose tissue were looked for as a cause of moderate primary hypertriacylglycerolemia (HTG) in five obese subjects. Comparison was made with six obese normolipidemic subjects. The two groups were matched for body weight, tolerance of intravenous glucose, fat cell size, fasting levels of serum immunoreactive insulin, and ser...

different solvent extracts of a red algae, hypnea flagelliformis,and two brown algae, cystoseira myrica and sargassum boveanum, collected from the persian gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (dpph) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (tlc)-bioautography, agar disc diffusion (add) ...
