Application

α-Ketoglutaric acid sodium salt has been used in the human kynurenine amino transferase II (KAT II) inhibition spectra assay.

Biochem/physiol Actions

α-Ketoglutaric acid is a key intermediate in the TCA Cycle. It also plays an important role in preventing nitrogen overload by combining with nitrogen released within the cell.
α-Ketoglutaric acid is the precursor for L-glutamic acid.

Oxidative cleavage of cycloalkene-1-carboxylates, made from the corresponding carboxylic acids, and subsequent oxidation of the resulting ketoaldehyde afforded the important 1-monoesters of 2-ketoalkanedioic acids. Thus ozonolysis of octyl cyclobutene-1-carboxylate followed by sodium chlorite oxidation afforded the 1-monooctyl 2-ketoglutarate. This is
