Biochem/physiol Actions

Stearidonic acid is an 18-carbon containing polyunsaturated fatty acid (PUFA). It belongs to the class of ω-3 fatty acids, which are dietary precursors to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Stearidonic acid is present in small amounts in seed oils.

Docosahexaenoic acid (DHA) plays important physiological roles in vertebrates. Studies in rats and rainbow trout confirmed that DHA biosynthesis proceeds through the so-called "Sprecher pathway", a biosynthetic process requiring a Δ6 desaturation of 24:5n-3 to 24:6n-3. Alternatively, some teleosts possess
