Lipase

Definition

Lipase is an enzyme that catalyzes the breakdown of fats into fatty acids and glycerol. It plays a crucial role in the digestive system by facilitating fat digestion and absorption.

5 Must Know Facts For Your Next Test

1. Lipase is produced primarily in the pancreas, but also in the mouth and stomach.
2. It is essential for the efficient digestion of dietary lipids.
3. Lipase activity increases when fats enter the small intestine, triggering hormone release that stimulates pancreatic secretion.
4. Deficiency in lipase can lead to malabsorption disorders such as steatorrhea.
5. Bile salts enhance lipase function by emulsifying fats, making them more accessible to enzymatic action.
