what serves as an emulsifying agent for fats in the small intestine?
Carbohydrates and proteins dissolve in water, which allows digestive enzymes to go to work on them, but fat does not. Your liver produces a substance called bile, which is secreted into the small intestine. This breaks up fat in a process called emulsification, which effectively make the fats water-soluble. Digestive enzymes in the small intestine can then break them down.
