摘要：

Positional distributions of fatty acids in dorsal muscle triacyl-sn-glycerols (TGs) were compared between the chum salmon, Oncorhynchus keta, caught on the coast and upstream at spawning season. The upstream salmon TGs contained 22:6 in the sn-1 and sn-3 positions at the concentrations higher than the coast salmon TGs. The level of it in the sn-2 position was not so different between them. The proportions of 16:0 in the sn-1 and sn-3 positions were much lower in the upstream salmon. TGs than in the coast salmon TGs. The upstream salmon TGs also contained lower proportions of 20:5 in the sn-2 and sn-3 positions and of 16:1 in the sn-2 position. Such differences in positional distribution confirmed the view that the depletion of TGs occurred unevenly during the migration from coast to upstream. The uneven depletion of TGs was found to depend on the position in which the fatty acids are esterified.
