What is Pyridoxine?

Pyridoxine is a hydroxymethylpyridine with hydroxymethyl groups at positions 4 and 5, a hydroxy group at position 3 and a methyl group at position 2. The 4-methanol form of vitamin B6, it is converted intoto pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. It has a role as a cofactor, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a member of methylpyridines, a vitamin B6, a monohydroxypyridine and a hydroxymethylpyridine.
