  1. Values (nanomole percent by weight composition) represent means ± standard errors. Means in the same row accompanied by asterisks are significantly different between treatments at LSD = 0.05, n = 12 per treatment group. D represents diacyl species. Monounsat, monounsaturated fatty acids; PBS, phosphate buffered saline solution; polyunsat, polyunsaturated fatty acids; PPA, propionic acid. Phosphatidylserine molecular species were identified using neutral loss scan of 185 D in ESI positive mode. The lipid components in the table are arranged based on the molecular species composition.
