What is the function of bile in digestion?

Explanation:
Emulsification of fats is the function of bile. Bile is released into the small intestine when fat enters and contains bile salts that are amphipathic. They coat large fat droplets and break them into many tiny droplets, dramatically increasing the surface area available for enzymes. This boosts the action of pancreatic lipase, which digests fats into fatty acids and monoglycerides for absorption. Bile doesn’t directly absorb fats, nor does it break down proteins or neutralize stomach acid—those roles belong to other digestive components.
