WebbPyruvate is converted into acetyl-CoA by the pyruvate dehydrogenase (PDH) complex, which is an important enzyme complex in the cellular metabolism of eukaryotic organisms since it is responsible for this conversion. It is made up of numerous copies of four different subunits, which are designated as E1, E2, E3, and E3BP respectively. WebbPyruvate dehydrogenase complex (PDC) deficiency is a type of metabolic disease. This means that the body is not able to efficiently break down nutrients in food to be used for energy.
