The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Nitric oxide triggered dephosphorylation reactionsEnemchukwu, Emeka Martin 01 1900 (has links)
The synergistic effect of nitric oxide toward dephosphorylation reactions involving phosphate esters was the subject of investigation in this research. Sodium nitroprusside under UV irradiations at 254nm, 365nm and white light was utilized as nitric oxide donor in solutions. The effects of cobalt trimethylenediamine and nitroprusside towards dephosphorylation of nitrophenylphosphate and pyrophosphate which were modeled as organophosphate ester substrates were also investigated. The activated substrate models showed more rate enhancement than the unactivated models in all cases. The direct interaction of nitric oxide with the phosphorus centre is presumed to be the reason for enhanced hydrolysis. This study demonstrates the possible role of nitric oxide in decontamination reactions of poorly biodegradable phosphate esters in the biosphere. / Chemistry / M. Sc. (Chemistry)
