吡哆素 维生素B6 Pyridoxine


Pyridoxine is the 4-methanol form of VITAMIN B6 that is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Pyridoxine (also called pyridoxol, not to be confused with pyridoxal) is one form of vitamin B6. Its hydrochloride salt, pyridoxine hydrochloride, is used as a vitamin B6 dietary supplement.

Chemical Properties

The appearance of Pyridoxine is needle crystals (acetone). Mp160 °C, it is easy to sublimate, LD50 (rat oral) 4000mg / kg.


Pyridoxine is a vitamin and can be used as a kind of additive in food., such as in sports nutrition food, juice (flavor) type drink, larger infant and toddler formula, biscuits and so on.

Pyridoxine has a role in transporting protein Bsu1. Pyridoxine contributes to thiamine uptake; characterization of thiamine (vitamin B1) transporter Thi9 from Schizosaccharomyces pombe.

Pyridoxine can be used as an intermediate in synthesizing 4-Pyridoxic Acid-d3 (P991877), an isotope labelled analog of 4-Pyridoxic Acid (P991875); which is a catabolite of vitamin B6 (P991735). Also a water-soluble B-group vitamin that can be used as a urinary diagnostic biomarker for determining the nutritional status of these vitamins.
