Which enzyme digests protein?

Question: which enzyme digests protein?


Protease is an enzyme that digests proteins.

  • It breaks down proteins into smaller peptide chains and amino acids through a process known as proteolysis.
  • There are several types of proteases, For example
  • Trypsin
  • Chymotrypsin
  • Pepsin
  • Papain etc.


Protease Location Function
Trypsin Small Intestine Digests proteins into smaller peptides
Chymotrypsin Pancreas,

Small Intestine

Cleaves proteins into smaller peptide fragments
Pepsin Stomach Breaks down proteins into smaller peptides
Papain Derived from papaya Used as a meat tenderizer and digestive aid
Bromelain Derived from pineapple Assists in protein digestion
Cathepsins Lysosomes, various tissues Involved in intracellular protein turnover

Matrix Metalloproteinases (MMPs)


Extracellular matrix, various tissues


Regulate tissue remodeling and repair

Caspases Involved in apoptosis Responsible for programmed cell death
