WebPyruvic acid is a 3-carbon compound which is formed in glycolysis by the breakdown of glucose. Glucose is a 6- carbon compound with molecular formula C6H12O6 and breakdown of one molecule of glucose produces 2 molecules of pyruvic acid ( C3H4O3) which is a 3- carbon compound.

WebStep 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. This reaction creates a two-carbon hydroxyethyl group bound to the enzyme (pyruvate dehydrogenase). We should note that this is the first of the six carbons from the original glucose molecule to be removed.

WebAcetyl CoA: The glycolysis of a single glucose molecule gives two pyruvic acid molecules comprising three carbons each. Each of these pyruvate molecules undergoes acetylation and decarboxylation, to give Acetyl coenzyme A and carbon dioxide. Thus, each molecule of Acetyl CoA has two carbon atoms.
