Hydrogen Peroxide is Scavenged by Ascorbate-specific Peroxidase in Spinach Chloroplasts
, 1981Intact spinach chloroplasts scavenge hydrogen peroxide with a peroxidase that uses a photoreductant as the electron donor, but the activity of ruptured chloroplasts is very low [Nakano and Asada (1980) Plant & Cell Physiol. 21: 1295].

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

Synthesis of Copper Peroxide Nanodots for H2O2 Self-Supplying Chemodynamic Therapy.
Journal of the American Chemical Society, 2019Chemodynamic therapy (CDT) employs Fenton catalysts to kill cancer cells by converting intracellular H2O2 into hydroxyl radical (•OH), but endogenous H2O2 is insufficient to achieve satisfactory anticancer efficacy.

Hydrogen peroxide and hematin in microsomal lipid peroxidation
Journal of Inorganic Biochemistry, 1981Lipids of rat liver microsomes underwent peroxidation with production of malondialdehyde in the presence of H2O2 and hematin. Rates of peroxidation of 27-33 nmol of MDA formed/mg of microsomal protein/30 min were measured with 5 mM H2O2 and 10 microM hematin at 22 degrees C. Histidine (0.01 M) caused a 55% inhibition.

Lipid peroxidation and lipid peroxide detected by chemiluminescence
Free Radical Biology and Medicine, 1987This article emphasizes the advantages of using a luminescence spectrometer based on photon counting techniques for the detection of lipid peroxidation. An overview is presented of how chemiluminescence can be stimulated in the luminol-cytochrome c heme peptide system as an assay for lipid hydroperoxides.

Organic Peroxides, Hydrogen Peroxide, Epoxides, and Neoplasia
Radiation Research Supplement, 1963Preliminary 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 ...

Hematin- and peroxide-catalyzed peroxidation of phospholipid liposomes
Archives of Biochemistry and Biophysics, 1991The effect of hydroperoxides on hematin-catalyzed initiation and propagation of lipid peroxidation was examined utilizing soybean phosphatidylcholine liposomes as model membranes. Polarographic and spectrophotometric methods revealed a bimodal pseudocatalytic activity for hematin.

Hydrogen Peroxide: A Key Chemical for Today's Sustainable Development.
ChemSusChem, 2016The global utilization of hydrogen peroxide, a green oxidant that decomposes in water and oxygen, has gone from 0.5 million tonnes per year three decades ago to 4.5 million tonnes per year in 2014, and is still climbing.
