Notes: Leukoaminochrome is formed by cyclization of dopamine o-quinone to dopaminochrome. Oxidation of leukoaminochrome to dopaminochrome and polymerization of dopaminochrome to neuromelanin . The DA oxidation can occur spontaneously, is accelerated by transition metal ions (Mn2+ or Fe2+), or can be catalyzed by a number of different enzymes [HMDB]
