Norepinephrine sulfate

Plasma norepinephrine sulfate increases after sympathetic nervous system activation by an exhausting incremental exercise test and remain elevated up to 2 h after exercise. (PMID: 8330610). Human platelets contribute to the formation of plasma norepinephrine sulfate by norepinephrine uptake, intraplatelet sulfoconjugation and release of norepinephrine sulfate. (PMID: 7968241). Higher concentrations of norepinephrine sulfate in portal venous than arterial plasma indicate substantial production of norepinephrine by mesenteric organs. (PMID: 8627312). Intravenously infused norepinephrine is sulfoconjugated in humans, indicating that a major part of NE is sulfoconjugated in blood or at sites easily accessible from blood. (PMID: 12020748).
