what makes the bile that works to break down fats
By forming micelles, bile salts break up (or emulsify) large fat particles into smaller ones. The proteins associated with the micelle also attract the digestive enzyme lipase, which breaks down the fats inside the micelle into their component parts for absorption in the gut. Bile is an important player in the digestive system largely because it helps to digest fats. In the gut, fats exist as relatively large globs that cannot be absorbed. To prepare fats for absorption, they must first be broken down into their component parts. An enzyme called lipase (lip-, fat; -ase, break down) is capable of breaking down the large fat globs.
