Peroxy anion
WebPeroxynitrite (ONOO−) is an oxidant produced by the reaction between nitric oxide (NO) and superoxide radicals (O 2 − ). It is known to produce oxidative stress by virtue of LPO, methionine, and sulfhydryl group oxidation in proteins, antioxidant depletion, and … Webperoxy acid, also called Peracid, any of a class of chemical compounds in which the atomic group ―O―O―H replaces the ―O―H group of an oxy acid (a compound in which a hydrogen atom is attached to an oxygen atom by a covalent bond that is easily broken, producing an anion and a hydrogen ion). Examples of peroxy acids are peroxyacetic acid …

WebSep 1, 2002 · They constitute a class of materials that play an important role as catalysts for oxidation–reduction reactions. Of particular interest, the adsorption of atomic oxygen O at the anion site O 2− of the metal oxide surface. This process leads to the formation of the peroxide ion O 22−. WebAug 5, 2012 · This might be due to presence of bulky methyl group in E-isomer which hinders the attack of peroxy anion intermediate at reactive site of substrate. In the Z-isomer, hydrogen atom present at the opposite side provides enough space to incoming peroxy anion intermediate to react sufficiently with the substrate resulting in formation of epoxide.
