The reaction of hydrogen peroxide with copper顥竮inc bovine superoxide dismutase at ratios of 0.2 to 4.0 per active site at pH 10.0 results in the formation of distinct electrophoretic forms of the enzyme. The mobilities of these forms are identical to the mobilities of the forms present in ...
Im investigating the catalysis of hydrogen peroxide decomposition by copper (II) chloirde, and have come up with an interesting phenomena that i dont quite uderstand! Can someone help?! ok i have added 6ml of aqueous, 80% saturated, solution of copper (II) chloride to 60g 10% wt/wt co...

Re: Effects of hydrogen peroxide on copper « Reply #1 on: June 27, 2009, 07:56:36 PM » There are complex copper ions that are green in solution, eg. Cu4SO4(OH)6 and Cu2CO3(OH)3Also: http://en.wikipedia.org/wiki/Copper(II)_chloride Logged Something New Member Posts: 6...
(IV) provoked by them, whereas the inhibition effect produced by Cr(VI) on the Cu(II)/H2O2 reaction can be ascribed to its ability to act as an oxidative scavenger for Cu(I), thus preventing its participation as the initiator of a free-radical chain mechanism leading to the decomposition...
Endothelial cell injury due to copper-catalyzed hydrogen peroxide generation from homocysteine. We have examined whether the toxic effects of homocysteine on cultured endothelial cells could result from the formation and action of hydrogen peroxide. I...

Storage of hydrogen peroxide in insulated vessels should be avoided. Contamination of hydrogen peroxide solutions is a second major cause of accelerated decomposition, since many common materials act as catalysts for the decomposition reaction. Some contaminants can create rapid decomposition of hydrogen ...
The hydrogen peroxide dependent oxidation of the epinephrinecopper complex to adrenochrome is mediated by free copper ions. The oxidation is enhanced by chloride ions and by the presence of serum albumin. The reaction is not inhibited by SOD or by hydroxyl radical scavengers. The 2:1 epinephrine ...
