Although traces of fat digesting enzyme (gastric lipase) have been reported but due to its very little concentration, it is unable to start fat digestion in stomach. Fat digestion starts in duodenum with the help of bile salts & pancreatic juice but completes in small intestine.

1. Fat digestion starts in the stomach.
2. Fat digestion starts in the duodenum and completes in the stomach.
3. Fat digestion starts in the duodenum and completes in the small intestine.
4. Fat digestion starts in the stomach and completes in the small intestine.

Correct answer: Fat digestion starts in the duodenum and completes in the small intestine.

Solution

Fat digestion does not effectively begin in the stomach because gastric lipase is present only in trace amounts. It starts in the duodenum with bile salts and pancreatic juice, then is completed in the small intestine.
