The latter are now called enzymes
and were formerly
called soluble ferments
or chemical ferments
Ferments of the first class are as a rule simple
microscopic vegetable organisms, and the fermentations
which they engender are due to their growth and
development; as, the acetic ferment
, the butyric ferment
, etc. See Fermentation
. Ferments of the
second class, on the other hand, are chemical
substances; as a rule they are proteins 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. Before 1960 the term “ferment”
fell out of use. Enzymes are now known to
be globular protein
s, capable of catalyzing a wide
variety of chemical reactions, not merely hydrolytic.
The full set of enzymes causing production of ethyl
alcohol from sugar has been identified and individually
purified and studied. See enzyme
