WebHDL plays a primary role in the removal of excess cholesterol from cells and returning it to the liver, where it is metabolized to bile acids and salts that are eventually eliminated … WebChylomicrons. Chylomicrons are the largest and most buoyant class of lipoprotein. The major protein component is apo B-48 but they also contain apo A-I, apo A-II and apo A-IV. After secretion, they acquire apo E and apo C from HDL. Chylomicrons are formed in the intestine and are the transport vehicle for dietary fat.
