Solution
The correct option is B glutamic
Most standard amino acids lose their α-amino group early on in degradation through transamination, that is, transfer to an α-keto acid. Transamination is mediated by aminotransferase enzyme. This is specific for individual amino acids. Transamination is freely reversible; therefore, both glutamate and α-ketoglutarate are substrates of multiple transaminases. If amino groups are to be transferred between two amino acids other than glutamate, this will usually involve the formation of glutamate as an intermediate. The role of glutamate in transamination is only one aspect of its central place in amino acid metabolism.
Thus, the correct answer is 'Glutamic.'
