THE ISOLATION OF LYSOLECITHIN FROM HUMAN SERUM

Abstract
The analysis of a lipid extract of human serum by chromato-graphy on silicic acid columns or on silicic acid-impregnated filter paper revealed, in addition to the known phospholipids, the presence of a component which was characterized as lysolecithin. The phosphorus of this component was found to comprise 4.7% of the total lipid P of a sample of pooled sera from normal young males.
