  2. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

  3. Hydroperoxide - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxide

    Many industrial peroxides are produced using hydrogen peroxide. Reactions with aldehydes and ketones yield a series of compounds depending on conditions. Specific reactions include addition of hydrogen peroxide across the C=O double bond: R 2 C=O + H 2 O 2 → R 2 C(OH)OOH. In some cases, these hydroperoxides convert to give cyclic diperoxides:

  4. Hydroperoxyl - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxyl

    Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.

  5. Lipid peroxidation - Wikipedia

    en.wikipedia.org/wiki/Lipid_peroxidation

    Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, [1] resulting in the formation of peroxide and hydroperoxide derivatives. [2]

  6. Peroxide - Wikipedia

    en.wikipedia.org/wiki/Peroxide

    The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...

  7. Spectrophotometry - Wikipedia

    en.wikipedia.org/wiki/Spectrophotometry

    Spectrophotometry is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by colored compounds. Important features of spectrophotometers are spectral bandwidth (the range of colors it can transmit through the test sample), the percentage of sample transmission, the logarithmic range of sample ...

  8. Lactoperoxidase - Wikipedia

    en.wikipedia.org/wiki/Lactoperoxidase

    In mammals the source of hydrogen peroxide is one of the duox1 or duox2 enzymes which reduce dioxygen to H 2 O 2 by oxidizing NADPH. [24] In the laboratory the source of the hydrogen peroxide (H 2 O 2) usually is the reaction of glucose with oxygen in the presence of the enzyme glucose oxidase (EC 1.1.3.4) that also takes place in saliva.

  9. Ascorbate peroxidase - Wikipedia

    en.wikipedia.org/wiki/Ascorbate_peroxidase

    Heme peroxidases catalyse the H 2 O 2-dependent oxidation of a wide range of different, usually organic, substrates in biology. This enzyme belongs to the family of oxidoreductases, specifically those acting on a peroxide as acceptor (peroxidases). The systematic name of this enzyme class is L-ascorbate:hydrogen-peroxide oxidoreductase.
