Abstract

Phospholipids were isolated from sheep, Indian buffalo, and human milks, and their fatty acid compositions determined by gas chromatography. The specific distributions of fatty acids in phosphatidyl cholines (PC) and phosphatidyl ethanolamines (PE) were determined after phospholipase A hydrolysis.Fatty acid compositions and specific distributions were similar in sheep and buffalo milk phospholipids, and compared closely with those of bovine milk. Human milk phospholipids, particularly PE, contained much larger amounts of polyunsaturated acids, but negligible amounts of branchedchain acids. Palmitic and oleic acids were evenly distributed in human milk PC and PE, whereas they were preferentially located in the alpha' position in PC and PE of ruminant milks.The results are discussed in the context of current theories of lipid biosynthesis.
