Peptotoxine :: Peptotoxine (n.) A toxic alkaloid found occasionally associated with the peptones formed from fibrin by pepsinhydrochloric acid.
Trypsin :: Trypsin (n.) A proteolytic ferment, or enzyme, present in the pancreatic juice. Unlike the pepsin of the gastric juice, it acts in a neutral or alkaline fluid, and not only converts the albuminous matter of the food into soluble peptones, but also, in part, into leucin and tyrosin..

Enzyme :: Enzyme (n.) An unorganized or unformed ferment, in distinction from an organized or living ferment; a soluble, or chemical, ferment. Ptyalin, pepsin, diastase, and rennet are good examples of enzymes..
