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. WebChylomicrons are formed in the intestine and transport dietary triglyceride to peripheral tissues and cholesterol to the liver. The enzyme lipoprotein lipase, with apolipoprotein (apo)C-II as a co-factor, hydrolyzes chylomicron triglyceride allowing the delivery of free fatty acids to muscle and adipose tissue.
