Name the enzyme that emulsifies fat in the small intestine.

Bile from the liver emulsifies fats, and the enzyme lipase then breaks them down into fatty acids and glycerol.

• Bile role: Bile salts break large fat globules into small droplets (emulsification) increasing surface area.
• Enzyme action: Pancreatic lipase hydrolyzes the emulsified fats.
• Reaction: Fat + Water → Fatty acids + Glycerol (by lipase)
• Site: Duodenum and small intestine lumen.
