Erepsin

noun

1. An enzyme complex found in intestinal and pancreatic juices that functions in the breakdown of polypeptides into amino acids.
2. A ferment discovered by O. Cohnheim in the intestinal mucosa, which is capable of causing the cleavage of acid albumins and albumoses into crystalline end-products of proteolytic digestion, but which is without effect upon the native albumins. It acts in neutral or feebly alkaline media. A similar ferment has apparently been found also in the vegetable world.
