In a transamination reaction
WebTransamination is the transfer of an amine group from an amino acid to a keto acid (amino acid without an amine group), thus creating a new amino acid and keto acid as shown below. Keto acids and/or carbon skeletons … Web(A) a-ketoglutarate is always formed during a transamination between an amino acid and glutamate. (B) Transamination reactions produce glutamate that is deaminated after entering the urea cycle. (C) Free ammonia is removed from glutamate using glutamate dehydrogenase and NAD+ as an oxidizing agent.
