Conclusion
It is evident that vitamin B6 serves as a physiological antioxidant. The mechanism cannot be dependent solely on the chemical structure of the vitamin. Despite the favorable arrangement of the substituents, pyridoxine and its derivatives show no, or only slight, antioxidative activityin vitro. The inactivation apparently results from the nature of the pyridine ring.
Vitamin B6 is one of the B vitamins which are required for the normal metabolism of the fats and essential fatty acids. However it still remains to be investigated whether the vitamin is directly associated with fat metabolism or whether the vitamin itself is responsible for the maximum function or the synthesis of enzymes involved.
