• Hydroxyl radical - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl_radical The hydroxyl radical, • OH, is the neutral form of the hydroxide ion (OH −).Hydroxyl radicals are highly reactive (easily becoming hydroxy groups) and consequently short-lived; however, they form an important part of radical chemistry. Most notably hydroxyl radicals are produced from the decomposition of hydroperoxides (ROOH) or, in atmospheric chemistry, by the reaction of excited atomic ...

    www.sciencedirect.com/topics/.../hydroxyl-radical Hydroxyl radical is the most reactive oxygen species and can react effectively with organic and inorganic matter as well as cell constituents of organisms. Cheng Wang, in Sweet Potato Processing Technology, 2017. Hydroxyl radicals are a type of free radical with the most active chemical properties. They have a high reaction rate constant and ...
  • Hydroxyl Radical - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/earth-and-planetary-sciences/hydroxyl-radical The hydroxyl radical (HO•), the three-electron reduction product of molecular oxygen, is the most reactive species of oxygen. It has a half-life in biological systems of about 1 ns and reacts with organic molecules at rates that approach diffusion-limited, with rate constants of 10 9 –10 10 M −1 s −1 (Buxton et al. 1988).This high reactivity makes HO• very unselective in preferences ...

Hydroxyl free radicals OH. are an ultimate oxidation species — able to attack and oxidize molecules in their vicinity in order to balance their unpaired electron configuration. Hydroxyl radical molecular configuration source. Hydroxyl or hydroxy groups (OH) form hydroxy anions OH-, which carry a negative charge.
  • Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl A hydroxy or hydroxyl group is the entity with the formula OH. It contains oxygen bonded to hydrogen.In organic chemistry, alcohols and carboxylic acids contain hydroxy groups. Both the negatively charged anion OH −, called hydroxide, and the neutral radical ·OH, known as the hydroxyl radical, consist of an unbounded hydroxyl group.. According to IUPAC rules, the term hydroxyl refers to the ...
  • Hydroxyl radicals – friend or foe? | Blue Skies

    thepollutionreport.wordpress.com/2015/03/31/hydroxyl-radicals-friend-or-foe A free radical can be defined as an atom with at least one unpaired electron (most electrons comes in pairs). Free radicals such as the halogen atom are very reactive due to the unpaired electron. Bonding of one oxygen and one hydrogen atom creates the hydroxyl radical (OH•) and leaves one unpaired electron. The hydroxyl radical OH•…

    pubs.acs.org/doi/10.1021/cr500310b The hydroxyl radical (•OH) is one of the most powerful oxidizing agents, able to react unselectively and instantaneously with the surrounding chemicals, including organic pollutants and inhibitors. The •OH radicals are omnipresent in the environment (natural waters, atmosphere, interstellar space, etc.), including biological systems where •OH has an important role in immunity metabolism.
