The standard deviations, … Abstract: Alternative methods for the synthesis of pyridoxine have been investigated. Pyridoxamine is a monohydroxypyridine that is pyridine substituted by a hydroxy group at position 3, an aminomethyl group at position 4, a hydroxymethyl group at position 5 and a methyl group at position 2. Full text Full text is available as a scanned copy of the original print version. Pyridoxine, also known as vitamin B 6, is a form of vitamin B 6 found commonly in food and used as dietary supplement. To define the pathway enzymatically, we established an enzyme reaction system with a crude enzyme solution of R. meliloti IFO14782.
