Detailed explanation-1: -Hydrochloric acid (HCl) in the stomach begins protein digestion by denaturing the protein, denaturation results in the loss of the protein’s function. HCl also converts inactive pepsinogen to its active form, pepsin. Pepsin begins breaking the peptide bonds between amino acids.
Detailed explanation-2: -Hydrochloric acid denatures proteins in the stomach. This is because it is a strong acid and dissociates to give hydrogen ions. These ions break the complex protein structures and make the amino acids of the protein more accessible to digestive enzymes.
Detailed explanation-3: -Hydrochloric acid contributes to protein digestion by supplying H+ which activates pepsinogen, the precursor to pepsin. Pepsinogen is secreted by chief cells in the gastric glands of the body and antrum of the stomach.
