what do bile salts do in digestion
The bile salts help to break down the fat molecules into   smaller parts, and they are then easily digestible by the small and   large intestine.   After the bile salts are done doing their job, they are returned back   to the liver and recycled, and are used again when they are needed.ile salts do this by forming a spherical structure around globs of fat in the gut; this spherical structure (in combination with a few other proteins that get added to it) is called a micelle.
