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.
