Metabolite Identification
Common NameDopamine 4-sulfate
DescriptionDopamine 4-sulfate is one of the metabolic products of the endogenous catecholamine dopamine which have also been implicated as intermediate in noradrenaline biosynthesis. In human blood circulation endogenous dopamine exists predominantly in the sulfated form and dopamine sulfate accounts for more than 90% of all dopamine. Sulfonation is the most important metabolic pathway that interferes with the binding of dopamine to its receptors. Dopamine-4-O-sulfate has concentrations about a 10th of those of the regioisomer dopamine-3-O-sulfate. It is believed that the vast majority of circulating dopamine sulfate originates in the upper gastrointestinal tract, and indeed that is the main site of expression of the enzyme responsible for its formation. Aryl sulfotransferase (SULT1A3, EC is an enzyme that catalyzes the sulfonation of many endogenous and exogenous phenols and catechols; the most important endogenous substrate is dopamine. SULT1A3 strongly favors the 3-hydroxy group of dopamine over the 4-hydroxy group and may indeed be primarily responsible for the difference between the circulating levels of dopamine sulfates in human blood.
