Stearidonic acid

Stearidonic acid (6Z,9Z,12Z,15Z-Octadecatetraenoic acid) is an intermediate fatty acid in the biosynthetic pathway from α-linolenic acid to VLC ω-3 PUFA. The conversion efficiency of stearidonic acid is higher than that of alpha-linolenic acid. Increasing the intake of stearidonic acid can increase the content of eicosapentaenoic acid (EPA) in red blood cells. Stearidonic acid can also be isolated from methanolic extracts of the brown alga Brachyphyllum gracilis[1][2].
