Oxidative Decarboxylation

A metabolic process in which a carboxyl group is removed from a molecule as CO2, typically coupled with the reduction of NAD+ to NADH.

Pyruvates

The ionized form of pyruvic acid, a key intermediate in several metabolic pathways, including glycolysis.

Acetyl CoA

A molecule that plays a key role in metabolism, serving as a substrate for the Krebs cycle and fatty acid synthesis; it links glycolysis and pyruvate oxidation with the citric acid cycle.
