Define Functions of Pyridoxine?

There are three different forms of vitamin B6, namely pyridoxine, pyridoxarnine, and pyridoxal. All three must be phosphorylated and the 5'-phosphates of the first two forms are oxidized to the functional pyridoxal phosphate (PLP), which serves as a carbonyl-reactive coenzyme to, a. number of enzymes involved in the metabolism of amino acids. Such enzymes include aminotransferases, decarboxylases, and dehydratases; δ-aminolevulinate synthase in haem biosynthesis, and phosphorylase in glycogen breakdown and sphingoid base biosynthesis. Let us study these functions in greater details.
