Abstract

Lipid and fatty acid compositions of the integument of the squid Ommastrephes bartrami, which is an industrial waste, were assessed for appraisal as a possible new source of phospholipids containing docosahexaenoic acid. Total lipid of wet and dry bases were 2.5 and 14.7%, respectively. Phospholipids was 80, 85% of the total lipid. The major phospholipids were sn-glycero-3-phosphocholine and sn-glycero-3-phosphethanolamine. The sn-glycero-3-phosphocholine consisted of 1,2-diacyl and 1-O-alkyl-2-acyl types, and sn-glycero-3-phosphoethanolamine consisted of 1,2-diacyl, 1-O-alkyl-2-acyl and 1-O-alk-1'-enyl-2-acyl types. Docosahexaenoic acid was a major fatty acid in both 1,2-diacyl and 1-O-alkyl-2-sn-glycero-3-phosphocholine, comprising 49.1 and 77.3 mol% of the total compositional fatty acids, respectively. However, in 2-sn-glycero-3-phosphoethanolamines the major fatty acids were eicosapentaenoic acid (34.8 mol%) in 1,2-diacyl, doxosahexaenoic acid (65.1 mol%) in 1-O-alkyl-2-acyl-, and eicosapentaenoic acid and docosahexaenoic acid (42.9 and 41.2 mol%, respectively) in the 1-O-alkl'-enyl-class. The carbon chain-lengths of the major alkenyl group in 1-O-alk-1'-enyl-2-acyl-sn-glycero-3-phosphoethanolamine were 16 and 18.
