nmdcat.online June 27, 2026

The process of lipid digestion in the small intestine involves the emulsification of large fat globules into smaller micelles, a process fundamentally aided by the amphipathic nature of

A. Pepsin

B. Amylase

C. Bile salts

✓

D. Hydrochloric acid

📝 Explanation

Bile salts are amphipathic cholesterol derivatives secreted from the liver. Their hydrophobic side associates with lipid droplets, and their hydrophilic side faces the aqueous intestinal fluid. This coating breaks large globules into smaller ones (micelles), vastly increasing the surface area for lipase action.
