Question

The vast majority of fat digestion occurs in the 1._____________ portion of the GI tract. It begins when triglycerides are emulsified by 2. _ from the gallbladder. The bile was originally made by the 3._ and is made of cholesterol with a small amino acid attached. (p.206 of text) This substance from the gall bladder coats the fat and forms a lipid droplet called a 4._. An enzyme called 5._ is then released by the 6._ and that enzyme will break down triglycerides into monoglycerides, 7._, and 8._. 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 long chain fatty acids and 9._ recombine to form triglycerides and these join with fat soluble vitamins, proteins, 10.__________________________________________ _ and 11.________________ to form the 12._, which is one of several lipoproteins that transport lipids in the blood. The chylomicron will move into the 13._ system and eventually enter the blood stream. In contrast to the above mentioned lipids, the glycerol and the 14. ____ are smaller compounds and can move directly into the cell and on to the 15._.
