Trypsin
Trypsin , noun
[Greek {not transcribed} a rubbing, from {not transcribed} to rub, grind. So called because it causes protein to break up or to fall apart.]
(physiol.) A proteolytic 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.
