Content of lecithin as related to the total content of phospholipids was increased in alpha-lipoproteins of healthy men with hyper-alpha-lipoproteinemia (concentration of cholesterol exceeded 72 mg% in the lipoproteins). The alpha-lipoproteins accumulated considerably more free cholesterol than its esters; this caused a decrease in the molar ration "phospholipids/free cholesterol". The surface of phospholipid-cholesterol monolayer of alpha-lipoproteins is apparently responsible for retaining of increased amounts of cholesterol in the complex as well as for participation of these structures in enzymatic reactions in blood serum.

UI MeSH Term Description Entries
D008075 Lipoproteins, HDL A class of lipoproteins of small size (4-13 nm) and dense (greater than 1.063 g/ml) particles. HDL lipoproteins, synthesized in the liver without a lipid core, accumulate cholesterol esters from peripheral tissues and transport them to the liver for re-utilization or elimination from the body (the reverse cholesterol transport). Their major protein component is APOLIPOPROTEIN A-I. HDL also shuttle APOLIPOPROTEINS C and APOLIPOPROTEINS E to and from triglyceride-rich lipoproteins during their catabolism. HDL plasma level has been inversely correlated with the risk of cardiovascular diseases.

D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.
