15 صفحه اولDietary stearidonic acid is a long chain (n-3) polyunsaturated fatty acid with potential health benefits.
The therapeutic and health-promoting effects of (n-3) long-chain PUFA (LCPUFA) from fish are well known, although these same benefits may not be shared by their precursor, alpha-linolenic acid (ALA). World-wide agencies and scientific organizations (i.e. FDA, AHA, International Society for the Study of Fatty Acids and Lipids, Institute of Medicine, WHO, etc.) have made similar dietary recommend...
متن کاملPurification of cyclopiazonic acid by liquid chromatography.
A purification procedure for cyclopiazonic acid has been developed, using sequential preparative and semi-preparative liquid chromatography. Crude cyclopiazonic acid (324 mg) was extracted from a 1 L fermentation medium with chloroform-methanol (80 + 20), dried, dissolved in chloroform, and chromatographed on an oxalic acid/silica preparative column with chloroform-methanol (99 + 1) as the elua...
متن کاملAlgal biotechnology for pursuing omega-3 fatty acid (bioactive) production
Algae are spread in diversified ecosystems that include marine, freshwater, desert and hot springs and even snow and ice environments. Algae are classified as multicellular large sea weeds (macroalgae) or unicellular microalgae. Macroalgae are targeted for mining of natural biologically activecomponents,which includeproteins, linearpeptides, cyclic peptides, and amino acids. Recently, microalga...
متن کاملErythrocyte stearidonic acid and other n-3 fatty acids and CHD in the Physicians' Health Study.
Intake of marine-based n-3 fatty acids (EPA, docosapentaenoic acid and DHA) is recommended to prevent CHD. Stearidonic acid (SDA), a plant-based n-3 fatty acid, is a precursor of EPA and may be more readily converted to EPA than a-linolenic acid (ALA). While transgenic soyabeans might supply SDA at low cost, it is unclear whether SDA is associated with CHD risk. Furthermore, associations of oth...
