The Bond Dissociation Energy of Peroxides Revisited.

Journal of Physical Chemistry A, 2020
When dealing with organic peroxides in both laboratory and industrial applications, the relative strengths of the O-O bond is of vital importance, both from a safety and mechanistic perspective.

Stochastic protein alkylation by antimalarial peroxides.

ACS Infectious Diseases, 2019
Antimalarial peroxides such as the phytochemical artemisinin or the synthetic ozonides arterolane and artefenomel undergo reductive cleavage of the pharmacophoric peroxide bond by ferrous heme, released by parasite hemoglobin digestion.

Organic Peroxides, Hydrogen Peroxide, Epoxides, and Neoplasia

Radiation Research Supplement, 1963
Preliminary data are reported that support the suspicion that organic peroxides may possess carcinogenic properties. This suspicion in large measure relates to the acknowledged mutagenicity of certain peroxides. As a possible mechanism of action it is suggested that peroxides may act by catalyzing the depolymerization of deoxyribonucleic (DNA) and ...

Coulometric microdetermination of peroxides—II☆Organic peroxides

Talanta, 1973
An iodometric method for the rapid microdetermination of organic peroxides, utilizing electrochemical reduction in the iodine-iodide system, has been developed. After complete reaction between peroxide and iodide in an acidic semi-aqueous medium the iodine produced is reduced at a rotating platinum electrode, at constant potential.

Peroxides and Mutations

Radiation Research Supplement, 1963
The role of peroxides, produced by radiation or oxidative processes in metabolism, in the production of mutations is reviewed. Results are reported from studies on living cells immersed in peroxides modified in various ways. Results are used to postulate the action of internally formed peroxides on the hereditary substance. It is concluded that it will

Coulometric microdetermination of peroxides—I. Hydrogen peroxide

Talanta, 1973
An electroanalytical method, based on controlled-potential coulometry in the iodine-iodide system, has been developed for determination of small amounts of hydrogen peroxide. The sample is added to an electrolyte containing an acid solution of iodide and the iodine, which is produced rapidly, is reduced at a rotating platinum electrode.

Hydrogen peroxide signalling

Current Opinion in Plant Biology, 2002
Recent biochemical and genetic studies confirm that hydrogen peroxide is a signalling molecule in plants that mediates responses to abiotic and biotic stresses. Signalling roles for hydrogen peroxide during abscisic-acid-mediated stomatal closure, auxin-regulated root gravitropism and tolerance of oxygen deprivation are now evident.

Hydrogen Peroxide Poisoning

Toxicological Reviews, 2004
Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products.
