Stearidonic acid (all cis-6,9,12,15)

C18:4 (all cis-6,9,12,15) fatty acid; Moroctic acid

This product is a high purity polyunsaturated fatty acid that is ideal for analysis and biological studies. Recently it has been found that conjugated stearidonic acid can be produced by the bacteria bifidobacteria and propionibacteria from stearidonic acid, suggesting an as yet unexplored pathway of stearidonic acid in mammals through intestinal microbes.1 Stearidonic acid, along with similar polyunsaturated fatty acids, demonstrates inhibitory effects on the 5-lipoxygenase pathway,2 tumor necrosis factor,3 and prostoglandin E2,3 thereby suppressing inflammation. Stearidonic acid is the product of the rate-limiting step in the synthesis of eicosapentaenoic acid from alpha-linolenic acid and is thus more readily converted to eicosapentaenoic than is alpha-linolenic acid.4 Eicosapentaenoic acid has been shown to lower the risk of cardiovascular disease and stearidonic acid is therefore also important in reducing this risk.4 Much research is currently being carried out to try to introduce more stearidonic acid into the human diet.
