WebbThe pyruvate dehydrogenase (PDH) complex catalyzes the overall, irreversible conversion of pyruvate to acetyl-CoA and CO2, and thereby links the glycolytic pathway to the tricarboxylic cycle. This complex contains multiple copies of three enzymatic components: PDH (E1 or PDHE1-A type I), dihydrolipoamide acetyltransferase (E2), and lipoamide … 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. Symptoms of PDC deficiency include signs of metabolic dysfunction such as extreme tiredness (lethargy), poor feeding, and rapid breathing (tachypnea).
