Web18 de fev. de 2024 · Once formed, chylomicrons are transported from the intestinal lining to the lymphatic system and will soon be released into the bloodstream via the jugular vein in the neck. Chylomicrons transport food fats perfectly through the body’s water-based environment to specific destinations such as the liver and other body tissues. WebChylomicrons are formed in the endoplasmic reticulum in the small intestine’s absorbent cells (enterocytes). The villi, lined with the brush border microvilli, provide a large surface area for absorption. The newly formed chylomicrons are secreted through the basolateral membrane into blood vessels, where they join with lymph to become chyle. for your understanding email

WebChylomicrons 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.
