Lipid Composition of Human Serum Lipoprotein Fraction with Density Greater than 1.210.

Abstract

A human serum lipoprotein fraction with density greater than 1.210 has been separated by ultracentrifugation and found to contain about 8% of total serum phospholipid, non-phospholipid ester, presumably triglyceride, and little or no cholesterol. About one-half of the phospholipid was found to be in the form of lysolecithin, which in turn comprised about one-half of the total lysolecithin of serum.
