The component fatty acids of lipids from four species of flatfish (flathead flounder Hippoglossoides dubius, scalyeye plaice Acanthopsetta nadeshnyi, pointhead flounder Cleisthenes pinetorum herzensteini, and Korean flounder Glyptocephalus stelleri) caught in the Sea of Japan and Funka Bay, Hokkaido were examined using open-tubular gas-liquid chromatography.<br> About sixty fatty acids were observed. Tetracosahexaenoic acid was present as an unusual fatty acid, and the structure was determined as all-cis-6, 9, 12, 15, 18, 21-tetracosahexaenoic acid (24:6n-3) by spectrometric analyses.<br> In the flatfish examined, the lipids of flathead flounder captured in the Sea of Japan were found to be particularly rich in 24:6n-3 (6-9% of total fatty acids in the flesh, 3% in the liver, and 6% in the viscera). This acid was abundantly found in the triacylglycerols rather than the phospholipids.<br> The results of this study suggest that 24:6n-3 was primarily incorporated into flatfish tissues through their diets.
