Ferments of the second class, on the other hand, are chemical substances, as a rule soluble in glycerin and precipitated by alcohol. In action they are catalytic and mainly, hydrolytic. Good examples are pepsin of the dastric juice, ptyalin of the salvia, and disease of malt. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Ferment \Fer*ment"\, v. t.
