How does pepsin breakdown proteins?

Amino acid links: Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides.

Can you tell me if throughout digestion, hydrochloric acid (hcl) lowers the stomach's pH and this causes the enzyme?

Can you tell me if throughout digestion, hydrochloric acid (hcl) lowers the stomach's pH and this causes the enzyme?

Can you clarify?: The stomach ordinarily produces HCl lowering the pH and it is at this pH that the stomach enzymes work best. Further down, other enzymes are present that work at neutral pH. The stomach's acidity is largely about removing calcium from bits of bone. Does this answer your question? Best wishes. ...Read more
