The incorporation of (n-3) versus (n-6) fatty acids into membrane lipids is regulated by a number of different processes within the cell. It is generally accepted that a common 6-desaturase uses both linoleate and linolenate as substrates. Desaturation of linoleate and linolenate are generally considered to be the rate limiting steps in the biosynthesis of arachidonate and 20:5(n-3) respectivel...

Whole-body fatty acid analysis in rats has previously shown that 50-70% of dietary linoleate and alpha-linolenate is beta-oxidized to CO2 and that this value increases with refeeding after a single episode of fasting. Our hypothesis was that repeated fasting-refeeding or weight-cycling would increase the beta-oxidation of linoleate and alpha-linolenate thereby depleting their whole-body levels....

Biodiesel fuels consist of a mixture different fatty acid esters. The thermophysical properties the esters are decisive for combustion and storage. Especially density viscosity influence, e.g., energy density, spray quality lubrication in diesel engine. For some esters, several studies on can be found literature wide pressure reasonably temperature range. However, data at high pressures as well...

Background: Isolation of methyl gamma linolenate from Spirulina platensis using flash chromatography and its apoptosis inducing effect against human lung carcinoma A549 cell lines. Methods: Gamma linolenic acid is an important omega-6 polyunsaturated fatty acid (PUFA) of medicinal interest was isolated from microalgae Spirulina platensis using flash chromatography system (Isolera system) as its...

This study evaluated the microbial conversion of coconut oil waste, a major agro-residue in tropical countries, into single cell oil (SCO) feedstock for biodiesel production. Copra cake was used as a low-cost renewable substrate without any prior chemical or enzymatic pretreatment for submerged growth of an oleaginous tropical mangrove fungus, Aspergillus terreus IBB M1. The SCO extracted from ...

The capacity of liver to synthesize long-chain fatty acids is greatly enhanced during early linoleate deficiency in mice. The enzymes catalyzing the synthesis of fatty acids from acetate or malonyl CoA were measured directly in soluble fractions isolated from fiver. The period of dietary restriction of linoleate is also accompanied by a rapid fall in the relative linoleate content of the liver;...
