Common NameStearidonic acid
DescriptionStearidonic acid is found in dietary plant oils which are metabolized to longer-chain, more unsaturated (n-3) PUFA. These oils appear to possess hypotriglyceridemic properties typically associated with fish oils.(PMID: 15173404 ). Stearidonic acid may be used as a precursor to increase the EPA content of animal lipids and that combinations of gamma-linolenic acid and stearidonic acid eicosapentaenoic acid can be used to manipulate the fatty acid compositions of lipid pools in subtle ways. Such effects may offer new strategies for manipulation of cell composition in order to influence cellular responses and functions in desirable ways. (PMID: 15120716 ).
