2-METHYL-3-HYDROXY-4-HYDROXYMETHYL-5-CARBOXYPYRIDINE LACTONE Chemical Properties,Uses,Production

Uses

5-Pyridoxolactone is an intermediate in the synthesis of analogues of Pyridoxine (P991735), one of the vitamins of the B6 complex; present in many foodstuffs (yeast, liver and cereals). Pyridoxine has a role in transporting protein Bsu1, Pyridoxine contributes to thiamine uptake; characterization of thiamine (vitamin B1) transporter Thi9 from Schizosaccharomyces pombe.

Definition

ChEBI: A furopyridine that is furo[3,4-c]pyridin-3(1H)-one substituted by a hydroxy group at position 7 and a methoxy group at position 6. It is a metabolite of vitamin B6.

General Description

5-pyridoxolactone is a metabolite of vitamin B6.

Biochem/physiol Actions

5-Pyridoxolactone is a normal human metabolite of vitamin B6 metabolism.
