What is the enzyme present in gastric juice digests protein?

The enzyme present in gastric juice that digests proteins is pepsin. Pepsin is a protease enzyme that is secreted by the chief cells of the gastric glands in the stomach. It is active in the acidic environment of the stomach and breaks down proteins into smaller peptides. Pepsin is particularly important for the digestion of meat and other animal products. It works in conjunction with other enzymes, such as hydrochloric acid, to break down the complex proteins into smaller molecules that can be more easily absorbed by the body.
