Abstract
The fatty acid (FA) compositions of the phosphatidylcholines (PCs) and phosphatidylethanolamines (PEs) of the muscle tissues of 13 species from seven types of marine invertebrates have been studied. In the PCs and PEs of all the animals the main FAs were the 20:5ω3, 20:4ω6, 16:0, 18:1, and 18:0 acids, although the representatives of each type had their own specific features in their FA composition. The main FAs in the PCs and PEs in the majority of animals investigated coincided, although there were exceptions. The most promising sources for the directed isolation of PCs or PEs enriched with certain FAs have been determined. The highest level of polyenic FAs and the highest unsaturation index were found in representatives of theCoelenterata andEchinodermata (stars) types. It was shown that the amount of polyenic acids as a fraction of the sum of the acyl and alkenyl radicals in the majority of animals investigated was greater in the PCs than in PEs.
