Abstract: This study examined seasonal variations in fatty acid composition of the phospholipid (PL) fraction, triacylglycerol (TAG) fraction, and phospholipid subclass (phosphatidylcholine, PC; phosphatidylinositol, PI; phosphatidylserine, PS; and phosphatidylethanolamine, PE) of muscle tissue of Chondrostoma regium, a freshwater fish inhabiting the Munzur River (Turkey).It was found that the percentages of total monounsaturated fatty acids, myristic acid (C14:0), palmitoleic acid (C16:1n7), oleic acid (C18:1n9), linoleic acid (C18:2n6), and linolenic acid (C18:3n3) were higher in TAG fraction than in the PL fraction.The ratio of total polyunsaturated fatty acids to total saturated fatty acids was 1.44-1.85,the atherogenicity index ranged from 0.36 to 0.46, while the thrombogenicity index was determined to be between 0.17 and 0.21 in total lipids.The n3/n6 ratio ranged from 6.55 to 10.49.The fatty acid levels of the PL and PL subclasses, TAG, and total lipid were influenced by the season.Throughout the year, palmitic acid (C16:0), C18:1n9, eicosapentaenoic acid (C20:5n3, EPA), and docosahexaenoic acid (C22:6n3, DHA) were the most abundant in PC.In PE, the share of n3 fatty acids decreased from November to April, and percentages of EPA, DHA and docosapentaenoic acid (C22:5n3) were high among the n3 fatty acids.The predominant fatty acids in PI were stearic acid (C18:0) and arachidonic acid (C20:4n6), and throughout the year, the share of C18:0 was the highest in November.In the PS fraction, the percentages of C16:1n7 and C18:1n9 were high.In summary, C. regium can be deemed an excellent source of nutritionally valuable lipids and recommended for wider use in the human diet.
