Question

The amino acid which plays a central role in nitrogen metabolism is/are

• A. glutamic acid
• B. $\alpha$-ketoglutaric acid
• C. aspartic acid
• D. double aminated keto acids

Answer 1

The correct option is A glutamic acid

Primary products of assimilated ammonia are glutamine and glutamate, which constitute the central reservoir of nitrogen for many biosynthetic pathways. Glutamate is the principal source of nitrogen for the production of N-amine and is involved in transamination reactions at the core of amino acid metabolism.
