What is the role of bile acids in the digestion of lipids?

What will be an ideal response?


Answers will vary.
Bile emulsifies fats. That is, it breaks fat into many tiny droplets, called micelles, and forms a shell around the micelles that keeps the fat droplets suspended in the water-based intestinal contents. Emulsification increases the surface area of lipids and allows pancreatic lipase to efficiently break triglycerides into monoglycerides and free fatty acids.
