Effect of season on the fatty acid profile of total lipids, phospholipids and triacylglycerols in Mastacembelus mastacembelus (Atatürk Dam Lake, Turkey)

OpenAlex İngilizce

The present study investigated the lipid content and FA profiles of total lipids, phospholipids (PL) and triacylglycerols (TAG) of Mastacembelus mastacembelus from the Atatürk Dam Lake (Turkey). The results showed that the total lipid content of the dorsal muscle varied seasonally from 0.50% to 3.59%. Wide ranges of saturated fatty acids (SFAs) (36.21 to 50.52%) and polyunsaturated fatty acids (PUFAs) (25.22 to 42.02%) were found in the PL fraction. However, higher monounsaturated fatty acids (MUFAs) (37.63 to 45.07%) and SFA (34.71 to 38.82%) were found in TAG (triacylglycerol). The ratios of ω-3 to ω-6 PUFA ranged from 0.65 to 1.32 and 1.07 to 3.48 in PL (phospholipid) and TAG fraction, respectively. The results also showed that the major components were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1ω-9), palmitoleic acid (C16:1ω-7), docosahexaenoic acid (DHA, C22:6ω-3), arachidonic acid (AA, C20:4ω-6) and docosapentaenoic acid (C22:5ω-3) in total lipid, C16:0, C18:1ω-9, AA and DHA in PL, C16:0, C16:1ω-7, C18:1ω-9, linoleic acid (LA, C18:2ω-6), and DHA in TAG extracted from the muscle of M. mastacembelus in all seasons.
