General description

Pyridoxal is a derivative of vitamin B6. Vitamin B6 derivatives contain a core pyridine ring. Pyridoxal consists of an aldehyde group at pyridine′s 4′ position. Pyridoxal is a water-soluble vitamin.

Application

For the labeling of amino acids and their detection in picomolar amounts; Coenzymes and Cofactors, vol. 1: Vitamin B6, Pyridoxal Phosphate

Biochem/physiol Actions

Vitamin B6 derivatives are initially oxidized to pyridoxal. It is then phosphorylated to pyridoxal 5′- phosphate (P5P). Pyridoxal 5′- phosphate is the circulatory form of vitamin B6.
