General description

Pyridoxal, a form of vitamin B6, is a water soluble vitamin. The food sources of vitamin B6 include grains, nuts, fruits, vegetables and meat.

Application

Pyridoxal hydrochloride has been used to test its potential contribution to plant stress tolerance. It has also been used as a supplement in modified M9 minimal medium to culture E. coli BL21(DE3) cells for expression of 15N-labeled ATG101.
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 plays a key role in metabolism of both carbohydrates and amino acids. It is implicated in the synthesis of neurotransmitters like dopamine from L-DOPA, serotonin from 5-HTP, and γaminobutyric acid (GABA) from glutamate. Vitamin B6 plays a major role in maintenance of a healthy nervous system.
