<prompt> Which amino acid undergoes hepatic deamination?AlanineGlutamateAspartateGlycine  <response>: Ans: B Glutamate Ref: Harpers Illustrated Biochemistry, 26th edition. Pg 244.Explanation:Since alanine is also a substrate for glutamate aminotransferase, all the amino nitrogen from amino acids that undergo transamination can be concentrated in glutamate. This is important because L- glutamate is the only amino acid that undergoes oxidative deamination at an appreciable rate in liver kidney.
