Ethanol

Entity

Ethanol

Final product of yeast's alcoholic fermentation.

It is a two-carbon alcohol, with the formula CH₃CH₂OH, produced by fermentation and by various industrial routes. It is a small, polar molecule that is miscible with water.

Ethanol is biologically important as a product of alcoholic fermentation and has applied relevance in beverages, biofuels, solvents, and disinfection. At high concentrations, it disrupts cellular membranes and proteins.

The video states that Saccharomyces cerevisiae produces it together with carbon dioxide when fermenting sugars without oxygen. It forms when acetaldehyde is reduced by alcohol dehydrogenase, regenerating oxidized NAD so glycolysis can continue.

    Luego, el acetaldehído se reduce a etanol por la alcohol deshidrogenasa, regenerando NAD oxidado a partir de NAD reducido.
