Enzymatic Activity of Pepsine

Which is the enzymatic activity of pepsine?

R/ Pepsin is one of three principal protein-degrading (a.k.a. proteolytic) enzymes in the digestive system so it helps with the breakdown and digestion of dietary proteins. I have attached a research paper with more information. Pepsin is porcine (pork) and Betaine is synthetic. Both are highest grade possible.
