Phosphatides of Normal Human Serum. Part I. Fractionation of the Phosphatides.

Abstract
Phosphatides of pooled, normal human serum were fractionated with chromatographic and hydrolytic methods. The following phosphatides were isolated in nearly pure state phosphatidylcholines, lysophospha-tidylcholines, phosphatidylethanolamines, lysophosphatidylethanolamines, phosphatidylinositols, lysophosphatidylinositols, acylated a-alkoxy-glycerophosphorylcholines, and finally, sphingomyelins. In addition concentrates of an unknown acidic glycerophosphatide as well as of native choline and ethanolamine plasmalogens and of acylated alkoxy-glycerophosphorylethanolamines were isolated.
