Scavengers catalytic

Finally, when OH is reduced by one electron it forms OH . The extreme reactivity of OH may preclude the existence of an enzyme which could catalytically scavenge it in any event, none is known.

Catalytic scavengers are enzymes or artificial catalysts capable of degrading OPs. These catalysts detoxify OPs by hydrolyzing the phosphoester (organophosphoms aeid anhydride hydrolase activity, also called phosphotriesterase aetivity) or lead to less toxic compounds by degrading their alkyl/aryl ehains through oxidation. 

Although most of the potential catalytic scavengers described here have not yet been tested for efficacy in animal models, they are indicative of the types of drugs that may soon be available for use in animals, including humans. Because mutations of BuChE, CaE, and PONl involve changes of internal amino acid residues in human proteins, the expectation is that these proteins would induce minimal immunological or behavioral side effects.

Thus, transition metals are capable of catalytically scavenging free radicals, as for copper in Fig. 4.5, if the copper concentration exceeds that of the hydroperoxide [38].
