Oxidative decarboxylation is a decarboxylation reaction caused by oxidation. Most are accompanied by α- Ketoglutarate α- Decarboxylation caused by dehydrogenation of hydroxyl carboxylic acids such as carbonyl carboxylic malic acid, isocitric acid, etc. [1]

Oxidative decarboxylation is a biochemical process in which a carboxyl group is removed from a molecule, releasing carbon dioxide and transferring electrons to an electron carrier. This reaction is crucial in cellular respiration as it links glycolysis to the citric acid cycle by converting pyruvate into acetyl-CoA, which then enters the cycle ...

Oxidative decarboxylation is a crucial metabolic process that converts pyruvate, the end product of glycolysis, into acetyl-CoA, a key entry point for the citric acid cycle.

2024年9月23日 · Under typical aerobic conditions in mammals, however, pyruvate is converted by a process called oxidative decarboxylation to give acetyl CoA plus CO 2. ( Oxidative because the oxidation state of the carbonyl carbon rises from that of a ketone to that of a thioester.)

2022年7月20日 · This equation expresses what happens in the process known as respiration: the oxidative breakdown of glucose to form carbon dioxide, water, and energy (in a non-biological setting, it is also the equation for the uncatalyzed combustion of glucose).

2022年11月23日 · The oxidative decarboxylation of isocitrate to alpha-ketoglutarate becomes catalyzed by NAD+ -dependent isocitrate dehydrogenase, producing CO2, NADH, and a proton; this is the rate-limiting step of the TCA cycle.

Under aerobic conditions the oxidative decarboxylation of α-keto acids is catalyzed by large multienzyme dehydrogenase complexes that require NAD +, thiamin pyrophosphate (TPP), lipoic acid, and CoA for activity. The reaction proceeds by the TPP-mediated decarboxylation of the acid to give an anionic hydroxyalkyl–TPP intermediate, which ...

Oxidative decarboxylation connects glycolysis to the citric acid cycle by converting pyruvate, the end product of glycolysis, into acetyl-CoA. This conversion occurs in the mitochondria and involves the removal of a carbon atom from pyruvate as …

2017年2月2日 · Oxidative decarboxylation of propionate 2 requires Tyr145. The neutral Tyr145-O radical is depicted abstracting hydrogen (H ) from the propionate C β , though this is hypothetical. Transfer of an electron and proton to the ferryl of Compound II then leads to the ferric-OH complex of harderoheme III, from which water can ultimately depart.

2016年11月21日 · The pyruvate dehydrogenase, or PDH complex carries out the oxidative decarboxylation process that generates acetyl CoA from pyruvate. The PDH complex serves as the link between glycolysis and the citric acid cycle, and is required for oxidative metabolism.
