“…Usually, they are water-soluble and are based mainly on the pyridine ring as their molecular structures . An improper intake of vitamin B could affect detrimentally the metabolism of sugar, fat, and protein, and even bring about neurologic disorders and the decay of the immune function. , As is well-known, vitamin B6, a general name given to pyridoxine, pyridoxamine, pyridoxal, and their phosphorylated derivatives, , is one of the most important vitamins among all vitamin B complexes because of its wide functions in various systems of the body (immune system, nervous system, lipid metabolism, gluconeogenesis, hormone modulation, niacin formation, gene expression) . It participates in more than 100 enzymatic reactions in which the most striking function lies in its service as a cofactor for enzymes during the biosynthesis process of amino acid. , Accordingly the study on the vitamin B6 system has become an interesting subject.…”
