WebThe optimal pH for peptic activity is generally between 1.6 and 2.5, but the effect of pH may vary with the substrate. Pepsin is capable of hydrolyzing peptide bonds of most proteins, mucin being one important exception. Pepsin splits bonds involving phenylalanine, tyrosine, and leucine most readily but can hydrolyze almost all other peptide bonds. WebPepsin works best at the acidity of normal gastric juice, which has the pH that ranges between 1.5 and 2.5. It must be noted that the reaction for the conversion of pepsinogen into pepsin requires a pH value of less than 5. Pepsin is not effective in the intestine, as the gastric acids are neutralized, with the pH value being 7.
