Document Summary
Monoglycerides and fatty acids diffuse into intestinal cells. Short-chained fatty acids are water soluble and are taken by capillary to liver via the portal vein. Monoglycerides and long-chained fatty acids are used to reform triglycerides in the intestinal cells, packaged in a lipoprotein (chylomicron) and taken by the lymphatic system. Lipoproteins serve as transport vehicles for lipids from small intestine and liver to cells of the body. Chylomicrons (least dense, most fat, floats better) All made up of same 4 things- phospholipid, triglyceride, cholesterol, and protein. On the inside walls of capillaries is an enzyme called lipoprotein lipase, which breaks down tg into glycerol and fatty acids. Fatty acids are absorbed by the cells of the body. Most of the glycerol is taken up by the liver. After much of the tg is removed from the chylomicron, it is called a chylomicron remnant.
