Ethanolamine and choline phospholipids in nascent very-low-density lipoprotein particles.

OBJECTIVE: To establish methods to examine the polar lipids of triglyceride-rich lipoproteins (TRLs) and to examine postprandial changes in glycerophosphocholine (PC) and glycerophosphoethanolamine (PE) polar lipids and in the ratio of diacyl to alkenylacyl components. The membrane phospholipids of TRLs have received little attention. PC and PE constitute major fractions and both comprise diacyl- and alkenylacyl-phospholipids. There has been …
