The decomposition of pyruvic acid into acetaldehyde and carbon dioxide has already been fully discussed (Chapter VI).
The third stage of Lebedeff's theory postulates the intermediate formation of pyruvic acid.
(b) The pyruvic acid is then decomposed by carboxylase yielding aldehyde and carbon dioxide (equation 2, p. 109).
pyruvic acid py·ru·vic acid (pī-rōō'vĭk, pĭ-)
A colorless organic liquid formed as a fundamental intermediate in protein and carbohydrate metabolism.
A colorless organic liquid formed by the breakdown of carbohydrates and sugars during cell metabolism. It is the final product of glycolysis and is converted into acetyl coenzyme A, which is required for the Krebs cycle. It is also used in the body to synthesize the amino acid alanine. Chemical formula: C3H4O3.
