Main ChEBI Ontology Automatic Xrefs Reactions Pathways Models
ChEBI Name pyridoxine
Definition A hydroxymethylpyridine with hydroxymethyl groups at positions 4 and 5, a hydroxy group at position 3 and a methyl group at position 2. The 4-methanol form of vitamin B6, it is converted intoto pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid.

Roles Classification
Biological Role(s): Escherichia coli metabolite
Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.
Saccharomyces cerevisiae metabolite
Any fungal metabolite produced during a metabolic reaction in Baker's yeast (Saccharomyces cerevisiae ).
mouse metabolite
Any mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus).
An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).
human metabolite
Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
water-soluble vitamin (role)
Any vitamin that dissolves in water and readily absorbed into tissues for immediate use. Unlike the fat-soluble vitamins, they are not stored in the body and need to be replenished regularly in the diet and will rarely accumulate to toxic levels since they are quickly excreted from the body via urine.
(via B vitamin )
Application(s): nutraceutical
A product in capsule, tablet or liquid form that provide essential nutrients, such as a vitamin, an essential mineral, a protein, an herb, or similar nutritional substance.
