Vast majority of fat digestion occurs in the small intestines of the GI tract. It begins when triglycerides are emulsified by made by the and stored in the gallbladder. This substance from the gall bladder coats the fat and forms a lipid droplet called a. An enzyme calledis released by the pancreas and that enzyme will break down triglycerides into, glycerol and free fatty acids. This lipid droplet (with fat soluble vitamins and cholesterol included with the triglyceride break down products) will cross into the villi cell. Once in the cell, the longer chain fatty acids and monoglycerides recombine to form and these join with fat soluble vitamins, cholesterol, and protein to form the which is one of several lipoproteins that transport lipids in the blood. This specific lipoprotein will then move into the system and eventually enter the blood stream. In contrast to the above mentioned lipids, the glycerol and the short chain fatty acids are smaller compounds and can move directly into the cell and on to the.
