Whats pyruvate dehydrogenase complex?

Enzymes: Pyruvate dehydrogenase complex is a complex of three enzymes in the mitichondria that change the Amino Acid pyruvate into the molecule acetyl-coa by a process called pyruvate decarboxylation. Acetyl-coa is used in the citric acid cycle to make energy for cells the complex links the metabolic pathway that breaks down glucose (elemental sugar) to the citric acid cycle.
