When chylomicrons enter the peripheral circulation they come into contact with an enzyme, lipoprotein lipase (LPL), which is located on the endothelial surface of capillaries. What is it transporting? Chylomicrons are found in the blood and lymphatic fluid where they serve to transport fat from its port of entry in the intestine to the liver and to adipose (fat) tissue. Definition of Very-low-density lipoprotein. Chylomicrons. ; Chylomicrons are the transporters that carry fats from the intestine to muscle and other tissues that need fatty acids for energy or fat production.
