The answer is this: Why does bile only have physical digestive function? Bile secreted by the liver can digest fat, but it has no digestive enzymes.

Bile is the digestive juice secreted by the liver, which is stored in the gallbladder and contains no digestive enzymes. Bile passes through the bile duct and reaches the small intestine from the gallbladder. In the small intestine, the function of bile is called emulsification, which is to break down fat macromolecules into small molecules, but there is no chemical reaction, which is a series of physical effects. Bile is related to the digestion and absorption of fat, but it is not bile that hydrolyzes fat. Fat is hydrolyzed into fatty acids and glycerol by lipase in the small intestine, and then absorbed by intestinal villi epithelial cells.
