The fatty acids (FA) compositions and positional distributions in triacylglycerols (TAG) and phospholipids (PL) of five wild freshwater fish (Squaliobarbus curriculus, Erythroculter ilishaeformis, Pseudobagrus fulvidraco, Bostrichthys sinensis and Siniperca kneri Garman) from the Poyang Lake (the largest freshwater lake of China) were studied. For TAG, S. kneri German had the highest content (13.59%) of n-3 polyunsaturated fatty acids (PUFA) and E. ilishaeformis had the lowest ratio of n-6/n-3 (0.65). PL characterized high content of PUFA, which declined in the order of phosphatidylethanolamine (PE) > phosphatidylcholine (PC) > TAG. 9c11t-18:2 accounted for 6.38-50.77% of total conjugated linoleic acids (CLA). The highest level of odd-branched chain fatty acids (OBCFA) was 26.7% in B. sinensis. The study revealed that the distribution of FA among the sn-positions was not random: monounsaturated fatty acids (MUFA) and PUFA preferred in positions 1 and 3 and saturated fatty acids (SFA) in position 2 of TAG while SFA and MUFA predominated over sn-1-PL and PUFA over sn-2-PL. |
