What Is the Chemical Reaction for Fermentation?

The chemical reaction for fermentation is expressed as the chemical equation: C6H12O6 ? 2 C2H5OH + 2 CO2. Showing the alcoholic fermentation of glucose as chemical formula C6H12O6, this one glucose molecule is converted into two ethanol molecules expressed as 2C2H5OH and two carbon dioxide molecules expressed as 2CO2.

The result is ethanol and is expressed as chemical formula C2H5OH.

Alcohol fermentation is a common process used to produce bread, beers, wines and ethanol-based fuels. Also known as ethanol fermentation, it is a metabolic anaerobic process where yeast, a micro-organism, converts carbohydrates, such as simple sugars, into ethanol and carbon dioxide.
