The Vitamin B6 molecule in 3-D

The Vitamin B6 (pyridoxine) molecule - rotatable in 3 dimensions

There are actually 3 forms of vitamin B6: pyridoxine, pyridoxal, and pyridoxamine.

These are all based on pyridine with different side groups.

Inside the cell, each of these is converted into pyridoxal 5'-phosphate (PLP), which acts as coenzyme in the synthesis of amino acids and neurotransmitters, and other reactions.
It is involved in transamination reactions, some decarboxylation and deamination reactions of amino acids and in the amination of some sugars.
