Unknown Principle
Protein is decomposed in the stomach by the protein-splitting (=proteolytic) enzyme pepsin. The digestive enzyme pepsin, which occus in the stomach of man and animals, is most active at pH values between 1 and 3. Protein-splitting enzymes are used, e.g. in the production of quark, as meat tenderizers and to prevent protein precipitation in beverages. The action of different protein-splitting enzymes is tested in this experiment.
