| Abstract | The structure of bryozoan Flustra sp. fatty acids was investigated. It was shown that the main fatty acids (FA) of the animal are (as percent of total): 22 : 6(n-3), 23.3%; 20 : 5(n-3), 14.2%; 16 : 0, 10.2%; 16 : 1 (n-7), 7.7%; 18 : 0, 3.0%; 18 :1 (n-7), 2.8%; 16 : 2, 2.7%; 20 : 1, 2.3%; 14 : 0, 2.3%; 20 : 4(n-6), 2.1%; 16 : l(n-5), 1.8%; 22 : 5(n-3), 1.8%; 20 : 4(n-3), 1.4%; 18 : 4(n-3), 1.3%; phitanic acid, 1.0%; 16 : 4, 1.0%; 18 : l(n-9), 1.0%; 20 : 3(n-6), 1.0% and 16 : 3, 1.0%. Besides these common fatty acids, 2.7% of C20 : 2, 2.0% of C22 : 2 non-methylene-interrupted (NMI) dienoic FA and the extralong-chain polyenoic fatty acid (VLCPUFA) 24 : 6(n-3) were found among the lipids of this bryozoan, contents of which was 0.9% in total lipids, but as high as 3% in phosphatidylethanolamine. Thus, bryozoans present one more type of marine invertebrates, in which specimens of VLCPUFA were found. © 1996 MAHK Hayka/Interperiodica Publishing. |
