Long chain fatty acids, cholesterol and other hydrophobic molecules dissolves in the core and are transported to the surface of the enterocytes for processing. Emulsification: In the small intestine lipids are emulsified by … WebHow are chylomicrons metabolized? 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.
