Question

Describe the roles of Glutamete, Glutamine and Alanine in amino acid catabolism, respectively

Answer 1

Glutamate role in amino acid catabolism:  Glutamate plays a major catalytic role in the removal of alpha-amino nitrogen from amino acids through the transdeamination system that involves aminotransferases and glutamate dehydrogenase.

Glutamine role in amino acid catabolism: Glutamine is a major nitrogen carrier after amino acid degradation in the liver.

Alanine role in amino acid catabolism: Alanine along with Glutamine is a major nitrogen carrier after amino acid degradation and helps keep the level of toxic ammonia low.
