Definitions for "Zymase"
A soluble ferment, or enzyme. See Enzyme.
Enzymes present in yeast that catalyze fermentation of sugar into alcohol and carbon dioxide.
The enzymes excreted by yeast that actually do the work of fermentation. While this is so technical that most books do not even bother to mention zymase, it has yet another claim to fame. It is the root of the word Zymurgy which ends nearly all english language dictionaries.
