Resynthesized lipids are incorporated into chylomicrons for transport to the blood stream. This type of lipoprotein is associated exclusively with the intestinal mucosa. They are relatively large, between 50 and 200 ไมโครเมตร in diameter, and consist of a hydrophobic lipid core containing triacylglycerols, cholesterol and phospholipid coat. Their average composition is 85% triacyglycerol, 9 % phospholipid 4% cholesterol and cholesterol esters and 2% protein, mainly apolipoproteins B-48, C-II and C-III The synthesis of chylomicrons occurs on the mucosal cell Golgi bodies. The nascent chylomicrons are transported to the basal membrane of the mucosal cells and are then released into the lymphatic system.
