WebThe optimum pH for Pepsin activity is 2 – 4. Pepsin, available as freeze-dried powder and obtained from the stomachs of hogs and calves, is used in the laboratory analysis or hydrolysis of various proteins. Pepsin (along with other enzymes such as chymosin and rennet) is also used in the preparation of cheese and other protein-containing ... WebThe test tube that was incubated at 37 degrees that contained pepsin, BAPNA and pH 2.0 buffer had an optical density of 0.40. The test rube incubated at 10 degrees with the same content mentioned above has a lower optical density. It was .02, by lowering the temperature, pepsin's activity was slowed so it was not able to digest as much BAPNA.
