Pepsin has maximal activity in acidic environments, ideally around a pH of about 1.5 to 2. This is considered the “normal acidity of gastric juices.” It stops working properly once the pH level reaches about 6.5 or higher. It then causes pepsin to be neutralized and denatured.

WebbPepsin in alkaline conditions helps in the breakdown of fats. This makes it a good way to control blood sugar levels and improve the quality of your blood. It also helps in breaking down and removing the excess water from your bloodstream. However, pepsin loses its functional effectiveness in acidic conditions. 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 … Visa mer Pepsin /ˈpɛpsɪn/ is an endopeptidase that breaks down proteins into smaller peptides.
