WebPeroxynitrite anion (OONO−) and peroxynitrous acid (OONOH) have distinct patterns of reactivity (92), but for simplicity, the text refers to both as peroxynitrite. OONOH spontaneously decomposes via species resembling the reactive radicals, hydroxyl (OH⋅) and/or nitrogen dioxide (⋅NO2). http://www.vivo.colostate.edu/hbooks/pathphys/topics/radicals.html
