Protein digestion begins in stomach and gets completed in small intestine. The gastric juice is secreted by the gastric glands inside the stomach. Food becomes acidic on entering the stomach.
The food that enters the stomach becomes acidic on mixing with this gastric juice. Rennin, hydrochloric acid, mucus and pepsinogen are the main components of gastric juice. The hydrochloric acid breaks up the food bits and creates a medium so that pepsinogen can be converted into pepsin. Pepsin is a proteolytic enzyme. Pepsin gets activated by HCl and then converts the proteins into proteases and peptides.Proteins-------------------Pepsin------Proteoses + Peptides
Rennin is also a proteolytic enzyme and plays an important role in the coagulation of milk.
