Question

What part of the gastrointestinal tract is the predominant site of dietary fat hydrolysis? ​

Quizplus · Accepted Answer

The small intestine is the predominant site of dietary fat hydrolysis. Bile secreted by the liver emulsifies fat, making it more accessible to the enzyme lipase, which breaks down fat into fatty acids and glycerol. This process mostly occurs in the small intestine, specifically in the duodenum and jejunum.
