The products of this reaction are glycerol and 3x fatty acid molecules.

Bile acids act as a solute to cholesterol in the gallbaldder, preventing gallstone formation, help the absorption of fat soluble vitamins and emulsify fats so they are avalible to pancreatic lipase. Bile acid production is the only method for excreating excess cholesterol.
