What amino acid can be obtained by the reductive amination of γ-ketoglutaric acid

Glutamic acid

Explanation:

Reductive amination is a form of amination that involves the conversion of a carbonyl group to an amine via an intermediate imine. The carbonyl group is most commonly a ketone or an aldehyde. In this reaction, in the presence of enzyme glutamate dehydrogenase, ammonium ion directly combines with alpha-ketoglutaric acid, to form glutamic acid (amino acid) and for this to happen, a reduced coenzyme (NADPH) is required.

The biosynthesis of glutamic acid  can be obtianed from the reductive amination of γ-ketoglutaric acid

γ-Ketoglutaric acid is a common precursor in synthesis of glutamic acid. Addition of NADPH and ammonia or alpha amino acid with   γ-Ketoglutaric acid produces glutamic acid. Enzymes involved in this reduction amination  process are glutamate dehydrogenase and/or transaminase.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
