Production of Single Cell Oils Containing Novel C20 Polyunsaturated Fatty Acids.

Production of polyunsaturated fatty acids by microorganisms.

Eicosanoids are a group of oxygenated fatty-acid derivatives formed from C20 polyunsaturated fatty acids

derivatives of C20 polyunsaturated fatty acids (PUFAs). Two main pathways are involved in the production of eicosanoids. The lipoxygenase (LO) pathway transforms PUFAs into lipoxins, leukotrienes and monohydroxy fatty acids, whereas the cyclo-oxygenase pathway produces prostaglandins and thromboxanes. These pathways predominantly use two PUFAs, arachidonic acid (AA, 20:4n-6) and eicosapentaenoi...

Clinical applications of C18 and C20 chain length polyunsaturated fatty acids and their biotechnological production in plants

A potential revolution in fatty acid therapies is on the horizon. In recent years, the full magnitude of various fatty acid treatments and their overall importance to health has become increasingly apparent. Fetal and infant nutrition studies have clearly shown that fatty acid status at birth can have life long health implications affecting eye and brain function, insulin resistance and blood p...

Metabolic Effects of Polyunsaturated Fatty Acids in Chickens: A Review

Chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. Fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (PUFAs) are required for both animal and human health. The n-3 PUFAs, especially, eicosapentaenoic acid (EPA) and docosahexaenoic ...

Enzymatic preparation of structured oils containing short-chain fatty acids.

Structured oils prepared by enzymatic transacylation with triacylglycerols (TAGs) and various fatty acids (FAs) were characterized. Transacylation with trilaurin and saturated FAs (C4:0-C16:0) was performed using Lipozyme RM-IM under standard reaction conditions. The structured oils thus produced had transacylation ratios of 25-37%, as medium-chain FAs > long-chain FAs > short-chain FAs. This r...
