Reactive nitrogen intermediates

Webarise by peroxidase-catalyzed oxidation of halides. The reactive nitrogen intermediates (RNI) that most closely influence ROI levels are nitric oxide radical (NO or •NO), nitrogen dioxide radical (•NO 2), nitrite (NO 2 −), and peroxynitrite (ONOO−). Reactions Reactions of ROI and RNI are covalent but often reversible.
