pyridoxol

Pyridoxine (Vitamin B6) is the 4-methanol form of vitamin B6 and is converted to pyridoxal 5-phosphate in the body. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading.

Pyridoxine hydrochloride (Vitamin B6) is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

4-Pyridoxolactone (β-Pyracin) is a pivotal substrate in the vitamin B6 degradation pathway I, primarily involved in the vitamin B6 metabolism mediated by soil microorganisms. It serves as the specific substrate for 4-pyridoxolactonase, undergoing zinc-dependent lactone ring hydrolysis catalyzed by this enzyme to produce 4-pyridoxic acid.

Pyridoxine hydrochloride (Standard) is the analytical standard of Pyridoxine (hydrochloride), primarily used for research and analytical applications. Pyridoxine hydrochloride (Pyridoxol; Vitamin B6) is a pyridine derivative and an essential water-soluble vitamin. In Alzheimer's disease (AD) cell models, Pyridoxine exerts antioxidant effects by activating the Nrf-2/HO-1 signaling pathway, thereby alleviating oxidative stress-induced neuronal damage. It also serves as a critical cofactor in protein and lipid metabolism, as well as neurotransmitter synthesis.
