Metabolite Identification
Common Name4-Pyridoxic acid
Description4-4-4-pyridoxic acid, also known as 4-4-pyridoxic acid, belongs to the class of organic compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. 4-4-4-pyridoxic acid exists as a solid, possibly soluble (in water), and a strong basic compound (based on its pKa) molecule. 4-4-4-pyridoxic acid exists in all living organisms, ranging from bacteria to humans. 4-4-4-pyridoxic acid can be biosynthesized from pyridoxal; which is catalyzed by the enzyme aldehyde oxidase. In cattle, 4-4-pyridoxic acid is involved in the metabolic pathway called the vitamin B6 metabolism pathway.

Enzymes

Enzyme Details
1. Aldehyde oxidase 1
General function:
Nucleotide transport and metabolism
Specific function:
Oxidase with broad substrate specificity, oxidizing aromatic azaheterocycles, such as N1-methylnicotinamide, N-methylphthalazinium and phthalazine, as well as aldehydes, such as benzaldehyde, retinal, pyridoxal, and vanillin. Plays a key role in the metabolism of xenobiotics and drugs containing aromatic azaheterocyclic substituents. Is probably involved in the regulation of reactive oxygen species homeostasis. May be a prominent source of superoxide generation via the one-electron reduction of molecular oxygen. Also may catalyze nitric oxide (NO) production via the reduction of nitrite to NO with NADH or aldehyde as electron donor. May play a role in adipogenesis.
