Metabolite Identification
Common NameDopamine quinone
DescriptionDopamine-quinone is synthesized by oxidation of the catechol ring of dopamine. If this occurs within the neuronal cytosol, the quinone may react with cytosolic components, particularly with cysteine residues. (PMID: 12835101 ). Dopamine quinone is produce by the reaction between dopamine and oxygen, with water as the byproduct. The reaction is catalyzed by the tyrosinase precursor.
