Definition of zymase in English: zymasenoun ˈzʌɪmeɪz mass nounBiochemistry A mixture of enzymes obtained from yeast which catalyse the breakdown of sugars in alcoholic fermentation. Example sentencesExamples - Harden explained this by saying that a high-molecular enzyme, the zymase proper, was left on the filter, which let through a low-molecular complementary enzyme, which for the sake of brevity was called co-enzyme or co-zymase.
- The reaction is then carried out in presence of yeast, which contain two enzymes maltose and zymase.
- It was soon realized that the conversion of sugar into alcohol by means of yeast juice is a series of stepwise reactions, and that zymase is really a mixture of several enzymes.
- Even now the question remains open whether zymase can be added directly to the established list of enzymes.
- When alcohol is produced for human consumption, zymase - provided by yeast - is used as the catalyst.
