Abstract
    The incorporation in vivo of 14C-18:2 ω6 and 3H-20:4 ω6 fatty acids in phospholipids isolated from gills, hepatopancreas and hemolymph of the crab Carcinus maenas was analysed. PC was the most heavily labelled phospholipid from these ω6-unsaturated fatty acids and appeared to play an important part in the phospholipids metabolism in Crustaceans. The pathway of fatty acids synthesis in phospholipids of C. maenas seems to be similar to those described for mammals. It is at the level of tissue Pl of C. maenas that the renewal of the 20:4 ω6 fatty acid is the most important. It is suggested that the rapid reorganization of phospholipid molecular species composition in the crab is checked by deacylation—reacylation cycle.
