Pyruvate decarboxylase
ピルビン酸脱炭酸酵素びるびんさんだつたんさんこうそPyruvate decarboxylase is an enzyme that plays an important role in the alcoholic fermentation of alcoholic beverages. It breaks down pyruvate into acetaldehyde and carbon dioxide. During alcoholic fermentation, yeast breaks down sugars to produce ethanol. In the course of this process pyruvate is formed, and the action of pyruvate decarboxylase converts it into acetaldehyde. This reaction is essential for fermentation to proceed, and it is an important step that influences the flavor and aroma of sake.
