Proteins are digested in which organ?

Explanation:
Protein digestion starts in the stomach. The stomach’s acidic environment denatures proteins and converts the zymogen pepsinogen into pepsin, a protease that cleaves peptide bonds and begins breaking proteins into smaller peptides. Digestion continues later in the small intestine with pancreatic proteases, but the initial site where proteolysis occurs is the stomach.
