Which process involves the formation of non-essential amino acid from keto acid? 
Select and explain. 
A. Deamination, B. Transamination, C. Dehydrogenation, D. Oxidation
B: Transamination
Answer: B: Transamination 
Explanation: The alpha amino group of amino acid can be transferred to alpha keto acid to form the corresponding new amino acid and alpha keto acid .This is a impoant reaction in the body for the interconversion of amino acids and for the synthesis of non-essential aminoacids. For example: Aminogroup is exchanged between alanine and glutamic acid .In almost all cases,the amino group is accepted by alpha ketoglutaric acid so that glutamic acid is formed.
