Pepsin is an enzyme which is secreted by Zymogen cells of  the stomach. First it is secreted in an inactive form called  Pepsinogen. After that Hydrochloric acid (HCl) activâ¦ates it  into pepsin. FUNCTION:   Its function is to hydrolyse the proteins to yield peptide. 7 people found this useful.
Confidence votes 106. Protein digestion in humans begins in the stomach. The enzyme pepsin is activated from its' inactive form pepsinogen due to the acidic conditions of the stomach. Pepsin starts digestion of proteins by breaking down the many of polypeptides into shorter peptides. However, complete chemical digestion will not occur until proteins reach the duodenum and the jejunum of the small intestine. Here more enzymes come into play (proteases and peptidases) so that the protein is completely broken down into its' smallest building blocks (the monomers called amino acids).
