Pepsin is most active in acidic environments between pH 1.5 to 2.5. Accordingly, its primary site of synthesis and activity is in the stomach (pH 1.5 to 2). In humans the concentration of pepsin in the stomach reaches 0.5 – 1 mg/mL. Pepsin is inactive at pH 6.5 and above, however pepsin is not fully denatured or irreversibly inactivated until pH 8.0. Therefore, pepsin in solutions of up to pH 8.0 can be reactivated upon r… WebPepsin has maximum activity at pH 2.0 and is inactive at pH 6.5 or higher. Although pepsin is inactive at pH 6.5 and above, it remains stable until pH 8.0 and can be reactivated when the pH is reduced. Pepsin is stable for at least 24 hours at pH 7.0, 37 degrees C and retains 79% +/- 11% of its original activity after re-acidification at pH 3.0.

Webit was found that pepsinogen, which is free of pepsin, does not activate at pH 4.4 during a 7-hour incubation period. Therefore, subsequent columns were run at pH 4.4. The flow rate was 1 ml per min and 2- to 3-ml fractions were collected at 13”. The protein fractions were pooled and dialyzed for 12 hours against two Changes ... WebThe low pH of the stomach is due to the secretion of HCl by the gastric glands. The strong acidity of the stomach denatures the proteins from ingested food, thereby increasing the exposure of the peptide bonds of protein. Pepsin works best at the acidity of normal gastric juice, which has the pH that ranges between 1.5 and 2.5.
