ChEBI Name	pyridoxal

ChEBI ID	CHEBI:17310

Definition	A pyridinecarbaldehyde that is pyridine-4-carbaldehyde bearing methyl, hydroxy and hydroxymethyl substituents at positions 2, 3 and 5 respectively. The 4-carboxyaldehyde form of vitamin B₆, it is converted into pyridoxal phosphate, a coenzyme for the synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid.

Roles Classification
Biological Role(s):	mouse metabolite Any mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus). human metabolite Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens). Saccharomyces cerevisiae metabolite Any fungal metabolite produced during a metabolic reaction in Baker's yeast (Saccharomyces cerevisiae ). Escherichia coli metabolite Any bacterial metabolite produced during a metabolic reaction in Escherichia coli. cofactor 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). 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. (via B vitamin )
