Most of the fat digestion occurs in

Options

A. rectum
B. stomach
C. duodenum
D. small intestine

Answer

D

Explanation

Fats are emulsified in small intestine by the detergent action of bile salts. Emulsification of fat converts large fat droplets into large number of small droplets, which provide larger surface area to lipases.
Then pancreatic lipase (steapsin) which is principal fat digesting enzyme, digest about `2/3^rd` of fats in these stages.
These intestinal lipase hydrolysis some tri, di and monoglycerides to fatty acids and glycerol molecules. So, the most of fat digestion occurs in small intestine.
