In the circulation, the triglycerides carried in chylomicrons are metabolized in muscle and adipose tissue by lipoprotein lipase releasing free fatty acids, which are subsequently metabolized by muscle and adipose tissue, and chylomicron remnants are formed. Chylomicron remnants are then taken up by the liver. Immature chylomicrons are transported from the smooth ER to the Golgi apparatus via SAR1B proteins, where they are processed, resulting in mature chylomicrons. Mature chylomicrons are secreted through the basolateral membrane into the lacteals, where they join lymph to become … Ver mais Chylomicrons (from the Greek χυλός, chylos, meaning juice (of plants or animals), and micron, meaning small particle), also known as ultra low-density lipoproteins (ULDL), are lipoprotein particles that … Ver mais Pancreatic lipases digest dietary triglycerides in the lumen of the small intestine, forming monoglycerides and fatty acids.
