  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. Phosphatidylinositol molecular species were identified using a precursor ion scan of m/z 241 in ESI negative mode. The lipid components in the table are arranged based on the molecular species composition.
