The process used in the conversion of pyruvate to acetyl

Decarboxylation or oxidative decarboxylation reaction is the biochemical reaction which uses pyruvate in order to form acetyl-CoA, by releasing NADH, which is a reducing equivalent, and carbon dioxide upon decarboxylation. We can observe such kinds of reactions in many organisms which are in between glycolysis and the citric acid cycle.
