Pepsin is the chief digestive enzyme in the stomach that breaks down proteins. We see that chief cells produce pepsinogen (an inactive form of pepsin). Pepsinogen is converted to pepsin when the parietal cells found within the gastric glands secrete hydrochloric acid.ucus that is produced by the epithelial cells of the stomach help protect the lining of the stomach from the corrosive hydrochloric acid and pepsin. If this protective lining fails, it can result in a peptic ulcer, which is a lesion of the mucosa.
