Question

Transamination reactions (or aminotransferases) .... a. Are an important first step in the breakdown of most fatty acids b. Usually require a=ketoglutarate as an acceptor of the nitrogen atom c. A and B d. None of the above

Answer 1

aminotransferases are Usually requires ketoglutarate as an acceptor of the nitrogen atom.

Transamination process is a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to nonessential amino acids.

the Transamination process in biochemistry is accomplished by enzymes called transaminases or aminotransferases. α-ketoglutarate acts as the predominant amino-group acceptor and produces glutamate as the new amino acid.

Aminoacid + α-ketoglutarate ↔ α-keto acid + Glutamate
