In thermodynamics the system is a specific part of the universe that is being studied,often the system is a chemical reaction. The surroundings are all parts of the universe that arenot the system, typically everything outside the test tube.Â¥ An open system can exchange both energy and matter with its surroundings.
Pepsin splits proteins into water-soluble fragments called peptones. Although this ordinarily occurs in the stomach, it can be duplicated in a large reaction vessel on a commercial basis. Partial digestion by pepsin can be used in food applicationsâfor instance, in the processing of soy protein and gelatin.
Nature of Pepsin: Pepsin functions in acidic environment with pH of 1.5 to 2. Pepsin gets denatured if the pH is more than 5.0. Pepsin needs optimum temperature of range 37 degree C to 42 degree C (ideal temperature in the human body).It is potently inhibited by the peptide inhibitor pepstatin.ature of Pepsin: Pepsin functions in acidic environment with pH of 1.5 to 2.
