PC, phosphatidylcholine; PE, phosphatidylethanolamine: PS,phosphatidylserine; PA, phosphatidic acid; PG, phosphatidylglycerol; SM,sphingomyelin

Total glycerophospholipid concentrations (PC, PE, PS, PA) in mouse, sheep and cow kidney were 34.7, 32.8 and 40.7 μmol g–1 tissue,and for brain were 74.7, 96.7 and 101.3 μmol g–1 tissue. Phosphatidylinositol concentration was negligible

Values are mean ± s.e.m. (N=4). ND, not detected. Superscript letters indicate significant differences between species at P<0.05: m, mouse; s, sheep; c, cow
