Outline the digestion of fats

In the small intestine , bile salts emulsify fats. They lower the surface tension of the fats , that is , they reduce the attractive forces between the fat molecules . This causes the fats to break into tiny fat droplets suspend in water , forming an emulsion . Note that this is just a physical break -up , but no chemical digestion of fat molecules has occurred . Emulsification increases the surface area to volume ratio of the fats , speeding up their digestion by lipase.

Emulsified fats are digested by lipase (pancreatic and intesɠintestinal lipases ) to fatty acids and glycerol . Thus the end - products of fat digestion are fatty acids and glycerol .
