Bile acid is the main active component of bile. It is a series of sterols produced in the process of cholesterol metabolism in animals. The main components are cholic acid, deoxycholic acid and chenodeoxycholic acid, which have multiple biological activities.
Two major functions: improve fat digestion and absorption, protect liver and gallbladder health.
Emulsification - emulsification of fat particles into smaller fat particles to expand the contact area of lipid and lipase.
bile acid can combine with lipase, open the cover structure of lipase, expose the catalytic group, change the structure of lipase, dredge the hydrophobic channel, and make the lipid drop enter the channel under the action of catalytic group, and decompose the lipid droplet into free fatty acid, free fatty acid, and so on Glycerol, monoglyceride, etc.
Only when free fatty acids combine with bile acids, can they be recognized and enter intestinal epithelial cells.
