Özet
Fatty acid (FA) compositions of total lipid,
phospholipid (PL) and triacylglycerol (TAG) fractions
have been determined in muscle tissues of Silurus triostegus.
The distributions of saturated fatty acid (SFA),
monounsaturated fatty acid (MUFA) and polyunsaturated
fatty acid (PUFA) proportions were found to be different
among total lipid, PL and TAG fractions from lipids in
muscle tissues of the male and female S. triostegus in all
seasons. Triacylglycerol contained a lower proportion of
PUFA and a higher proportion of MUFA and SFA than PL
while PL contained higher proportion of PUFA than proportion
of MUFA and SFA compared to TAG. Triacylglycerol
and PL fatty acid compositions in muscle tissues
of the male and female fish species were found different.
The most abundant fatty acids in the investigated seasons
were palmitic acid (C16:0), stearic acid (C18:0), oleic acid
(C18:1 n-9), palmitoleic acid (C16:1 n-7) and docosahexaenoic
acid (C22:6 n-3). It was shown that the total lipid
content and FA compositions in muscle tissues of the male
and female S. triostegus were influenced by reproduction
period and season.
