chy·mo·sin (kiґmo-sin) [EC] an enzyme of the hydrolase class that catalyzes the cleavage of a single bond in casein to form soluble paracasein, which then reacts with calcium to form a curd, insoluble paracasein. It is found in the fourth stomach of the calf and other ruminants. A commercial preparation, rennet, is used for making cheese and rennet custards. Called also rennin (not to be confused with renin).
