Protease

Definition

Protease is an enzyme that breaks down proteins into smaller peptides or amino acids. It plays a crucial role in the digestive process by facilitating the absorption of nutrients in the intestines.

5 Must Know Facts For Your Next Test

1. Protease is primarily produced in the stomach, pancreas, and small intestine.
2. The main types of proteases include pepsin, trypsin, and chymotrypsin.
3. Optimal activity of proteases depends on the pH level; for example, pepsin works best in acidic conditions.
4. Protease deficiency can lead to incomplete digestion of proteins and gastrointestinal issues.
5. Protease supplements are sometimes used to aid digestion in individuals with enzyme deficiencies.
