α-Ketoglutaric acid (English: α-Ketoglutaric acid) is one of the two keto-containing derivatives of glutaric acid (if not specifically stated, the term "ketoglutaric acid" mostly refers to α type. β-ketoglutarate is only different in the position of the keto group, and is not commonly used). The anion of this substance, α-ketoglutarate is an important biological compound. It is the keto acid product of glutamate deaminization and an intermediate product of the tricarboxylic acid cycle.

Uses: To determine the substrates of aminoconverting enzymes and dehydrogenases, to determine the supporting reagents of liver function, and also to be used as intermediates in organic synthesis.
Uses: Mainly used as a component of sports nutrition drinks
Uses: Used as a raw material for medicines, health products and food additives as an analytical reagent for tryptophan; as a substrate for the determination of transaminase and dehydrogenase; as a supporting reagent for the determination of liver function. It is a derivative of valeric acid. Glutamate dehydrogenase catalyzes the intermediate product of the KREB cycle.
