What is the role of bile salts in lipid digestion?

Bile salts act as emulsifiers to break down large fat globules into smaller droplets, increasing the surface area for lipase action.

How do phospholipases contribute to lipid digestion?

Phospholipases hydrolyze phospholipids into fatty acids and other components, facilitating lipid digestion.

Explain the mechanism of action of pancreatic lipase in lipid digestion.

Pancreatic lipase breaks down triglycerides into fatty acids and glycerol, allowing for their absorption in the small intestine.
