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. WebApr 10, 2024 · In acidic environments with a pH of 1.5 to 2.5, pepsin is most active. Pepsin works best at temperatures between 37 and 42 degrees Celsius. As a result, the stomach is the main site of synthesis and function (pH 1.5 to 2). In humans, pepsin concentrations in the stomach range from 0.5 to 1 mg/mL.
