Question

Refer to the given reaction. What does it depict?
A. Oxidative amination
B. Reductive amination
C. Transamination
D. Deamination

Answer 1

An amino acid is an organic molecule made up of an amino group, an acidic carboxyl group, and an R group that is unique to each amino acid. In an amination reaction, an amine group is introduced into an organic molecule. Amination reactions are significant as organonitrogen compounds are pervasive. Amino acids are the building blocks of proteins. They are involved in the growth and development, digestion and provide energy for the body.

Complete answer:
A very important reaction for the biosynthesis of amino acid is transamination.
The transamination reaction involves the transfer of amino groups from already synthesized amino acids to the keto acid. The transamination reaction is catalyzed by the enzyme known as transaminases.
By the transamination reaction, a large number of amino acids are synthesized.
These are the organic molecules that contain nitrogen.
The integration of amino groups from ammonium into keto acids describes the major step for the synthesis of nitrogenous organic molecules.
Oxidative deamination involves the conservation of glutamate to alpha-ketoglutarate.
Oxidative deamination is the method used for the synthesis of amino quinones.
Reductive amination is the conversion of the carbonyl group into an amine through an intermediate imine.
Deamination is the process of removal of an amino group from a molecule.
So, the correct answer is “Option C”.

Additional Information:
Transamination is a reversible reaction.
Alpha-ketoglutarate and glutamate are the substrates of multiple transaminases.
Transamination occurs in the cytoplasm.
Hydrolysis of ATP is involved in transamination.

Note:
In the transamination reaction, amino groups are removed from amino acids and are moved to acceptor keto-acids to form the amino acid version of the keto-acid and the keto acid version of the amino acid. Transamination reactions play a significant role in the coordination and regulation of the metabolism of amino acids and carbohydrates. Enzyme transaminases are used in the process of transamination. Transaminases are present in all living cells.
