Vitamin B6 (pyridoxine) enters in the organism and after that it is transformed
to pyridoxalphosphate, cofactor of many enzymes, which participate in the regulation
of the protein and lipid metabolism. Pyridoxine activates the processes of resorption
of amine acids in the intestine and its transition into the tissues and cells, as
well as the reabsorption in the kidney. It participates in the amine acid metabolism
- converts the glutamate (stimulating CNS mediator) to γ-aminobutyric acid (GABA,
inhibiting CNS mediator). Pyridoxine is of importance for the synthesis of siderophyline,
which transports iron in the blood, and also it is of value for tryptophan transformation
to nicotinic acid and serotonin. Vitamin B6 facilitates the utilization of the non-saturated
fat acids. It plays an important role in coenzyme A, purine, pyrimidine, and nucleic
