Hydrochloric acid is secreted by the gastric glands present on the walls of the stomach. It dissolves bits of food and creates an acidic medium. The acidic medium allows pepsinogen to be converted into pepsin. Pepsin plays a very important role in the digestion of proteins. Therefore, if HCl weren’t secreted in the stomach, then pepsin wouldn’t be activated. This would affect protein digestion. A pH of about 1.8 is important for proteins to be digested. This pH is achieved by HCl.Answered by Pragya Singh | 1 year ago
