Which protein-digesting enzyme is present in pancreatic juice?

Answer :

The main protein-digesting enzyme in pancreatic juice is trypsin, which is initially secreted as trypsinogen.

In pancreatic juice, the main protein-digesting enzyme is trypsin. It is initially secreted in the inactive form known as trypsinogen. Upon reaching the small intestine, trypsinogen is activated by the enzyme enteropeptidase, converting it to trypsin.

Trypsin not only catalyzes the hydrolysis of peptide bonds specifically involving basic amino acids like lysine and arginine but also activates other proteolytic enzymes such as chymotrypsinogen to chymotrypsin, and procarboxypeptidase to carboxypeptidase.

Chymotrypsin and carboxypeptidase further aid in protein digestion by breaking down peptide bonds in different areas of the protein chain.

Answer:

trypsin

Explanation:

Pancreatic juice is produced by Pancreas and has many enzymes like trypsin, chymotrypsinogen, elastase, carboxypeptidase, and amylase. Out of these enzymes, Trypsin is the one that aids in the digestion of Protein.
