Dopamine 3-O-sulfate
Dopamine 3-O-sulfate is a sulfonated form of dopamine. In human blood circulation endogenous dopamine exists predominantly in the sulfated form and dopamine sulfate accounts for more than 90\\% of all dopamine. Dopamine-3-O-sulfate predominates in human plasma, with concentrations about 10-fold higher than those of the regioisomer dopamine-4-O-sulfate. Sulfonation is the most important metabolic pathway that interferes with the binding of dopamine to its receptors. The origins of this preponderance for Dopamine-3-O-sulfate have not been determined, although there has been speculation about the contribution of the specificity of transport proteins and/or arylsulfatases. It has also been proposed to depend on the regiospecificity of the metabolizing enzyme(s) for the 3-hydroxy group of dopamine. 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 2.8.2.1) 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.

Dopamine 4-sulfate
Dopamine 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.

p-Cresol sulfate
p-Cresol sulfate is a microbial metabolite that is found in urine and likely derives from secondary metabolism of p-cresol. It appears to be elevated in the urine of individuals with progressive multiple sclerosis (PMID:10775436). p-Cresol sulfate is the major component of urinary MBPLM (myelin basic protein-like material). p-Cresol sulfate is a small protein-bound molecule that is poorly cleared with dialysis. It has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Uremic toxins include other low-molecular-weight compounds such as indoxyl sulfate, 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid, and asymmetric dimethylarginine (PMID:18941347). It has also been linked to cardiovascular disease and oxidative injury. Higher levels are associated with overgrowth of intestinal bacteria from Clostridia species, including C. difficile. p-Cresol is generated by the partial breakdown of tyrosine and phenylalanine by a wide range of intestinal obligate or facultative anaerobes, including the genera Bacteroides, Lactobacillus, Enterobacter, Bifidobacterium, and especially Clostridium (PMID:2394806). p-Cresol sulfate is a microbial metabolite that is found in urine and likely derives from secondary metabolism of p-cresol.
