   A mother substance, or antecedent, of an enzyme or chemical
   ferment; -- applied to such substances as, not being
   themselves actual ferments, may by internal changes give rise
   to a ferment.

         The pancreas contains but little ready-made ferment,
         though there is present in it a body, zymogen, which
         gives birth to the ferment.              --Foster.
