After injection of acetate-1-^<14>C, polar lipids (PL) and neutral lipids (NL) were isolated from the whole body of the prawns, and the proportional radioactivity of individual fatty acids constituting PL and NL was investigated by using argentation thin-layer chromatography and preparative gas-liquid chromatography on 10% DEGS followed by radioactive measurements of the trapped samples. In both P.monodon and P.merguiensis, radioactivity was mainly associated with palmitic acid (16: 0), palmitoleic acid (16: 1), stearic acid (18: 0), and oleic acid (18: 1ω9) but scarcely or slightly with linoleic acid (18: 2ω6), linolenic acid (18: 3ω3), eicosapentaenoic acid (20: 5ω3), and docosahexaenoic acid (22: 6ω3). These results suggest that 18: 2ω6, 18: 3ω3, 20: 5ω3, and 22: 6ω3 may be essential for P.monodon and P.merguiensis.}, pages = {21--26}, title = {Biosynthesis of Fatty Acids from Acetate in the Prawns, Penaeus monodon and Penaeus merguiensis}, volume = {28}, year = {} }
