Pyruvic acid

Pyruvic acid is decarboxylated and reduced by NADH to form a molecule of carbon dioxide and one of ethanol.
C3H4O3 + NADH + H+ → CO2 + C2H5OH + NAD+
This accounts for the bubbles and alcohol in, for examples, beer and champagne.

Pyruvic acid is first altered in the transition reaction by removal of a carbon and two oxygens (which form carbon dioxide). When the carbon dioxide is removed, energy is given off, and NAD+ is converted into the higher energy form NADH.
