Stopped Flow Spectrophotometric Observation of Superoxide
There are few ways to develop a high concentration of superoxide in solutions of physiological significance, and by far the most useful of these, pulsed radiolysis of oxygenated solutions [1 ], requires very specialized and expensive research equipment. One of the long term goals of this laboratory has been to develop alternative procedures for examining the chemistry of superoxide ion in aqueo...
متن کاملA stopped-flow apparatus for infrared spectroscopy of aqueous solutions.
IR spectroscopy has been widely applied in the study of photo-activated biological processes such as photosynthesis, but has not been applied to the study of reacting systems which require rapid mixing of aqueous solutions. This has been due in part to the high pressure needed to make an aqueous solution flow rapidly through the 50 microns optical pathlength between the plates in an IR cuvette ...
متن کاملSynthesis of Copper Nanoparticles in Aqueous Ambient Using Dismutation Reaction
The present study has investigated the synthesis of copper nanoparticles via copper dismutation reaction in an aqueous solution and ambient conditions. Copper (II) chloride hydrate ( ), sodium oleate (SO), sodium chloride (NaCl) and ethylene diamine (EN) have been used as copper (I, II) ions source, surfactant, chloride ions supplier and ligand, respectively. Also, an amount of hydrochloric aci...
متن کاملOxoammonium cation intermediate in the nitroxide-catalyzed dismutation of superoxide.
Dismutation of superoxide has been shown previously to be catalyzed by stable nitroxide compounds. In the present study, the mechanism of superoxide (.O2-) dismutation by various five-membered ring and six-membered ring nitroxides was studied by electron paramagnetic resonance spectrometry, UV-visible spectrophotometry, cyclic voltammetry, and bulk electrolysis. Electron paramagnetic resonance ...
متن کاملStopped-flow spectrophotometric analysis of intermediates in the peroxo-dependent inactivation of cytochrome P450 by aldehydes.
The reaction of hydrogen peroxide and certain aromatic aldehydes with cytochrome P450BM3-F87G results in the covalent modification of the heme cofactor of this monooxygenase. Analysis of the resulting heme by electronic absorption spectrophotometry indicates that the reaction in the BM3 isoform is analogous to that in P450(2B4), which apparently occurs via a peroxyhemiacetal intermediate [Kuo e...
