α-Ketoglutaric acid (2-oxoglutaric acid) is one of two ketone derivatives of glutaric acid. The term "ketoglutaric acid," when not further qualified, almost always refers to the alpha variant. β-Ketoglutaric acid varies only by the position of the ketone functional group, and is much less common. Its carboxylate, α … See more Alanine transaminase The enzyme alanine transaminase converts α-ketoglutarate and L-alanine to L-glutamate and pyruvate, respectively, as a reversible process. Krebs cycle See more Longevity Studies have linked α-ketoglutarate with increased lifespan in nematode worms and increased healthspan/lifespan in mice. Immune regulation See more Click on genes, proteins and metabolites below to link to respective articles.

ΔG°' for this reaction is -7.2 kcal mol-1.

WebTwo carbon atoms are oxidized to CO 2, the energy from these reactions is transferred to other metabolic processes through GTP (or ATP), and as electrons in NADH and QH 2. The NADH generated in the citric acid cycle may later be oxidized (donate its electrons) to drive ATP synthesis in a type of process called oxidative phosphorylation. [6] WebIn step three, isocitrate is oxidized, producing a five-carbon molecule, α-ketoglutarate, along with a molecule of CO 2 and two electrons, which reduce NAD + to NADH. This step is …

WebThe citric acid cycle begins by acetyl-CoA (2 carbons) combining with oxaloacetate (4 carbons) to form citrate (aka citric acid, 6 carbons). A series of transformations occur before a carbon is given off as carbon dioxide and NADH is produced. This leaves alpha-ketoglutarate (5 carbons).
