Notes:
The lipids from dark and white muscle of white sucker (Catostomus commersoni) were fractionated by thin-layer chromatography and fatty acid composition of each lipid class studied by gas-liquid chromatography. Dark muscle had a higher content of total lipid than white muscle (6.2% vs 1.4%) which was mostly accounted for by triglycerides. Phospholipid (PL) concentration was 521 ± 47 and 395 ± 34 mg/l00 of dark and white muscle, respectively. Phospha-tidylcholine was the predominant PL class in both muscles though the concentrations of other PL classes were much higher in the dark muscle. Palmitic acid (16:0), palmitoleic acid (16:1 n7), oleic acid (18:l n9), eicosapentaenoic acid (20:5 n3) and docosahexaenoic acid (22:6 n3) were the major fatty acids present. White muscle contained higher percentages of polyunsaturated fatty acid (PUFA) than the dark muscle. The free fatty acid concentration was about the same (∼7%) in both dark and white muscle.
