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. WebPepsin 1 has the highest molecular weight (44 500), while the other pepsins have molecular weights around 35 000. The pH optimum against protein substrates for all pepsins is in the acidic range 1.9–3.6. Pepsin 1 secretion is elevated in peptic ulcer disease (PUD) and is therefore the pepsin associated with ulcers.
