the determination of the fatty acid composition of individual phospholipids , neutral lipids and unesterified fatty acids showed that choline-containing phospholipids ( pc and sphingomyelin ) were not as altered in their fatty acid pattern as anionic phospholipids ( pe , phosphatidylserine ( ps ) and phosphatidylinositol ( pi ) and lysophosphatidylcholine ( lysopc ) .
