Oxoglutarate

Description

2-Oxoglutaric acid

2-Oxoglutaric acid or alpha-ketoglutaric acid, C5H6O5, occurs under physiological conditions as the anion 2-Oxoglutarate2-, Og. 2-Oxoglutarate (alpha-ketoglutarate) is formed from isocitrate as a product of isocitrate dehydrogenase (IDH) in the TCA cycle, and is a substrate of oxoglutarate dehydrogenase (OgDH). The 2-oxoglutarate carrier exchanges malate2- for 2-oxoglutarate2- as part of the malate-aspartate shuttle. In the cytosol, oxoglutarate+aspartate are transaminated to form oxaloacetate+glutamate. Cytosolic malate dehydrogenase converts oxaloacetate+NADH to malate.

Abbreviation: Og
