Peroxiredoxins (Prxs) are a very large and highly conserved family of peroxidases that reduce peroxides, with a conserved cysteine residue, designated the "peroxidatic" Cys (CP) serving as the site of oxidation by peroxides (Hall et al., 2011; Rhee et al., 2012). Peroxides oxidize the CP-SH to cysteine sulfenic acid (CP-SOH), which then reacts with another cysteine residue, named the "resolving...

Fatty acid peroxides have been found in the atherosclerotic human aorta. Glavind found a correlation between the extent of the atherosclerotic changes and the content of lipid peroxides. These lipid peroxides are very toxic to the tissues. There are several compounds in the tissues to counteract the toxicity of peroxides in vivo, i.e. SH compounds, ascorbic acid, or tocopherol. · It may be infe...

A natural self-regeneration step for urea derived graphitic carbon nitride with platinum nanoparticles is found by simply opening the system to air in the dark under ambient conditions, following its solar-driven hydrogen production. The produced peroxides deactivate the graphitic carbon nitride. Release of weakly bound peroxides on the polymeric semiconductor surface is a crucial process for r...

This account highlights the development of efficient methods for generation alkyl radicals from organosilicon peroxides and their applications in selective alkylation reactions. Compared with commonly used organic peroxides, a more diverse range can be prepared as bench-stable radical precursors, use combination transition metal catalysts allows under mild conditions. Consequently, these have o...
