Die dehydrierende … SpletPyruvate Dehydrogenase complex (PDH) connects the citric acid cycle and subsquent oxidative phosphorylation to the glycolysis, gluconeogenesis and lipid and amino acid metabolism pathways. PDH function and structure PDH catalyzes the oxidative decarboxylation of pyruvate to produce acetyl coenzyme A (acetyl-CoA), NADH and CO 2.

SpletDie Glycolyse findet im Zytosol statt, die dehydrierende Decarboxylierung von Pyruvat durch die Pyruvatdehydrogenase (PDH) jedoch im Mitochondrium. Da die Fettsäuren im Zytosol synthetisiert werden, muss das Acetyl-CoA wieder dorthin geschafft werden. SpletPyruvate dehydrogenase (PDH) is a convergence point in the regulation of the metabolic finetuning between glucose and FA oxidation. Hence, PDH converts pyruvate to acetyl-coA, and thereby increases the influx of acetyl-coA from glycolysis into the TCA cycle. Pyruvate dehydrogenase kinase 4 (PDK4) is a regulator of PDH, as it inhibits PDH ...
