[Fatty acid composition of the lipids of the mantle and liver of cephalopod mollusks].
The authors studied tissue lipids of flesh and liver of squids, the most important industrial objects in the Far East basin. Among them there were Todarodes pacificus, Ommastrephes bartrami, Berrytenthis magester, Sepia officinalis. Total lipids in flesh fluctuated from 0.50 to 2.61%. The liver of all squid species contains from 15.00 to 54.6% of lipids. The sum of lipids in the cuttlefish liver is from 5.43 to 12.30%. Lipids in edible tissues contain high amounts (50-55%) of phospholipids and monoglycerides. The following saturated fatty acids (SFA) prevail: C16:0 (from 14.68 to 28.64%). C14:0 (from 0.24 to 2.23%), C12:0 (from 0.25 to 2.82%). The cuttlefish lipids are characterized by the highest level of monounsaturated fatty acids: C16:1 (10.51%). C22:1 (13.59%). The content of polyunsaturated fatty acids in lipids of Bartram and Comandor squids and cuttlefish comprises 47.59-49.84%. C20:5 (5.40-20.20%) promotes a normal functioning of the cardiovascular system. The level of SFA in the Bartram squid liver lipids is more than 2 times lower (33.28/14.17) than in the tissue lipids, while in the Pacific Ocean (17.59/13.23), Comandor (39.20/30.71) squids and cuttlefish (20.39/17.82) they are at about the same level. The lipids of Comandor squid liver contain 22.98% of C16:0. The levels of the following acids are especially high: C18:1 (5.66-25.18%), C16:1 (1.49-20.32%), C22:1 (2.49-8.69%), C22:5 (4.13-6.83%), C20:5 (6.16-10.68%), C22:6 (3.10-10.18%), C20:4 (2.4-22.06%).
