Question

Transamination is:
A. Transfer of an amino group from amino acid to a keto acid
B. Oxidation of ammonia
C. Amino-acid destruction
D. None of the above

Answer 1

Hint: Transamination is important for the production of non essential amino acids. It involves the transfer of an amino group from a molecule to another. It is essential for the redistribution of nitrogen-based amino groups. Its end product is urea which is also an extractor end product in humans and is derived from the amine group in the amino acid.

Complete answer: Transamination is referred to as a chemical reaction that involves the transfer of an amino group to a keto-acid to form new amino acids. The enzyme involved in the process is called transaminase. It helps in the formation of different amino acids. Transamination is an important reaction that involves the redistribution of an amino group and the production of non-essential amino acids. It involves the transfer of an amino group from a molecule to another. These reactions combine reversible amination and deamination and mediate redistribution of amino groups among amino acids. Transaminases are widely distributed in human tissues and are particularly active in heart muscles, liver, skeletal muscles and kidney.
So, the correct answer is option A.

Additional information: Compounds containing chiral amine units can be synthesised using transaminases as biocatalysts during the process. This application has found use in the pharmaceutical, agrochemical, and other chemical synthesising industries. There are several other potential uses of the transaminase enzymes in the production of compounds complex in nature and chemical structures.

Note: All of the amino acids except lysine, threonine, proline and hydroxyproline participate in transamination reactions. There is a thorough rearrangement of the bonds during amination and deamination reactions.
