Trypsin and milk experiment temperature
WebThe effect of temperature on the rate of the reaction catalysed by trypsin Casein is a protein found in milk. Trypsin is an enzyme that digests casein. When trypsin is added to a dilute solution of milk powder, the casein is digested and the solution goes clear.
