  2. Boyland–Sims oxidation - Wikipedia

    en.wikipedia.org/wiki/Boyland–Sims_oxidation

    Some competitive oxidation of the nitrogen has been observed. [3] Behrman has shown that the first intermediate in the Boyland–Sims oxidation is the formation of an arylhydroxylamine-O-sulfate (2). [5] Rearrangement of this zwitterionic intermediate forms the ortho-sulfate (5), which then hydrolyses to form the ortho-hydroxyl aniline.

  3. Aniline - Wikipedia

    Likewise, it is also prone to oxidation: while freshly purified aniline is an almost colorless oil, exposure to air results in gradual darkening to yellow or red, due to the formation of strongly colored, oxidized impurities. Aniline can be diazotized to give a diazonium salt, which can then undergo various nucleophilic substitution reactions.

  4. Oxidizing agent - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_agent

    The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

  5. Oxidative stress - Wikipedia

    en.wikipedia.org/wiki/Oxidative_stress

    Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

  6. Aniline (data page) - Wikipedia

    en.wikipedia.org/wiki/Aniline_(data_page)

    Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...

    Studies have demonstrated that the glucose-alanine cycle may play a direct role in regulation of hepatic (liver) mitochondrial oxidation, particularly during periods of extended fasting. [9] Hepatic mitochondrial oxidation is a key process in the metabolism of glucose and fatty acids, involving the Citric Acid Cycle and oxidative ...

  9. Isotope effect on lipid peroxidation - Wikipedia

    en.wikipedia.org/wiki/Isotope_effect_on_lipid...

    Unlike catabolic oxidation of drugs, or oxidative damage to DNA or proteins (which occurs stoichiometrically), oxidation of PUFAs is particularly pernicious, proceeding through a non-enzymatic lipid peroxidation chain reaction (LPO), whereby a single ROS species can initiate a runaway autoxidation process that does not need any additional ROS ...
