Chapter 26.3, Problem 5QQ

Interpretation Introduction

Interpretation: Identify the reaction in which a derivative of pyridoxine (vitamin ${\text{B}}_{\text{6}}$) is required as a coenzyme.

Concept introduction: Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone.

Transamination reaction is a biochemical reaction that involves the transfer of an amino group. In transamination reaction exchange of an amino group from an $\text{α-amino}$ acid with a keto group of an $\text{α-keto}$ acid. There occurs no net loss or gain of amino acid in transamination reaction.

A biochemical reaction in which an $\text{α-amino}$ acid is converted into $\text{α-keto}$ acid along with the release of an ammonium ion is known as oxidative deamination reaction.
