ren·nin 'ren-ən n a crystallizable enzyme that coagulates milk, that occurs esp. with pepsin in the gastric juice of young animals and is obtained as a yellowish powder, grains, or scales usu. by extraction of the mucous membrane of the fourth stomach of calves, and that is used chiefly in making cheese and casein for plastics called also chymosin

n.
an enzyme produced in the stomach that coagulates milk. It is secreted by the gastric glands in an inactive form, prorennin, which is activated by hydrochloric acid. Rennin converts caseinogen (milk protein) into insoluble casein in the presence of calcium ions. This ensures that the milk remains in the stomach, exposed to protein-digesting enzymes, for as long as possible. The largest amounts of rennin are present in the stomachs of young mammals.
