One of the most important parts of bile is the bile salts. The bile salts do not function as digestive enzymes, but they do aid in digesting process. Bile salts enhance the absorption properties of the fatty acids and certain fat-soluble vitamins. When they do, the form fat globules. The masses of fat formed are difficult to digest, and this is where bile salts come in.
Bile salts cause fat globules to break up.
This makes it easier for fat-splitting enzymes to digest the fat molecules. The process of breaking up fat globules is called emulsification. A majority of the pancreas is made up of the cells that produce pancreatic juice. Pancreatic lipase is the enzyme that digests fat. Carboxypeptidase, chymotrypsin, and trypsin areprotein-splitting enzymes.
