The hydroxyl radical, •HO, is the neutral form of the hydroxide ion (HO–). Hydroxyl radicals are highly reactive and consequently short-lived; however...

neutral radical HO·, known as the hydroxyl radical, consist of an unbonded hydroxy group. According to IUPAC definitions, the term hydroxyl refers to...

radicals have short lifetimes. A notable example of a radical is the hydroxyl radical (HO·), a molecule that has one unpaired electron on the oxygen atom...

relatively stable precursors to hydroxyl radicals. 60%–70% of cellular DNA damage is caused by hydroxyl radicals, yet hydroxyl radicals are so reactive that they...

propagation, and termination. In the initiation phase, a pro-oxidant hydroxyl radical (OH•) abstracts the hydrogen at the allylic position (–CH2–CH=CH2)...

chemical. The corresponding electrically neutral compound HO• is the hydroxyl radical. The corresponding covalently bound group –OH of atoms is the hydroxy...

oxidative potential of the positive holes oxidizes water to create hydroxyl radicals. It can also oxidize oxygen or organic materials directly. Hence,...

generates hydroxyl radicals through Fenton chemistry. The hydroxyl radicals can then react with the nucleic acid molecules. Hydroxyl radicals attack the...

hypochlorous acid (HClO), and free radicals such as the hydroxyl radical (·OH), and the superoxide anion (O2−). The hydroxyl radical is particularly unstable and...

the reactive oxygen species generated, e.g., O− 2 (superoxide radical), OH (hydroxyl radical) and H2O2 (hydrogen peroxide). Further, some reactive oxidative...

with hydroxyl radical (•OH) to produce a radical intermediate •HOCO, which transfers rapidly its radical hydrogen to O2 to form peroxy radical (HO2•)...

peroxide. Some prominent ROS are hydroperoxide (O2H), superoxide (O2-), hydroxyl radical (OH.), and singlet oxygen. ROS are pervasive because they are readily...

DNA can become cross-linked. Oxidative free radicals, such as the hydroxyl radical and the superoxide radical, can cause DNA damages, and such damages have...

and electron. The hydroxyl radical transfers its radical to DNA. Or together with hydronium and electron, a free hydroxyl radical can damage the base...

CH• 3 It can also be produced by the reaction of methane with the hydroxyl radical: OH• + CH4 → CH• 3 + H2O This process begins the major removal mechanism...

(CH−3), methylium cation (CH+3) or methyl radical (CH• 3). The anion has eight valence electrons, the radical seven and the cation six. All three forms...

Iron(II) is oxidized by hydrogen peroxide to iron(III), forming a hydroxyl radical and a hydroxide ion in the process. Iron(III) is then reduced back...

major factor implicated in the free-radical theory of aging, based on its ready conversion into a hydroxyl radical. Eggs of sea urchin, shortly after fertilization...

formation of hydroxyl radicals (·OH) through ozone photolysis. Since the major sink of methane in the atmosphere is by reaction with •OH radicals, the NOx...

vocalist OH, the hydroxy functional group OH−, hydroxide anion •OH, hydroxyl radical OH, the alcohol class of compounds, that possess a hydroxy functional...

the air for up to a week. It decomposes by reacting with oxygen and hydroxyl radical to form formyl cyanide and formaldehyde. Acrylonitrile is harmful to...

interface. Hydroxyl radical(•OH) and H+ accumulate rapidly at the bubble interface. Ozone reacts with hydroxyl ions and hydroxyl radicals will form. The...

byproduct of the oxidation of carbon monoxide and of hydrocarbons by the hydroxyl radical. Because dielectric constant has a strong effect on pKa, and the dielectric...

intermediates that include the superoxide radical (O2−) and the hydroxyl radical (OH•), as well as the non-radical species hydrogen peroxide (H2O2). These...

reacts with the hydroperoxyl radical (HO• 2) to form nitrogen dioxide (NO2), which then can react with a hydroxyl radical (HO•) to produce nitric acid...
