Application
2-Ketoglutaric acid is a derivative of glutaric acid. It plays an important role in the metabolism of microbial cells and It acts as precursor for the synthesis of amino acids and nucleotides. α-ketoglutaric acid along with L-arginine can undergo reduction with sodium cyanoborohydride to form the diastereomers, nopaline and isonopaline. α-ketoglutaric acid can be prepared in 1:1 and 2:1 L-arginine alpha-ketoglutarate for sports nutrition. mainly as an ingredient in sports nutrition drinks.
