Medida da capacidade antioxidante de fluidos biologicos por voltametria de pulso diferencial associada ao uso de surfactante como resposta as adaptações geradas pelo exercicio

TL;DRAbstract

Increasing formation of oxygen reactive species, as a consequence of increasing in the energetic demand, can raise the cellular oxidation state, and it contributes to an optimum cellular redox state and for the development of maximum force. The biological samples reducing power reflects its antioxidant capacity, which is maintained mainly by the low molecular weight antioxidants (LMWA). LMWA act as reducing agents, they donate electrons to radicalar species. They can be, on this way, quantified by electrochemical techniques. LMWA include substances such as uric acid, vitamins C and E vitamin and lipoic acid. The aims of the present work were to investigate the applicability of the surfactant cetilpiridine chloride as a micellar system for the optimization of differential pulse voltammetry technique (DPV) for the analysis of human serum and saliva samples. It was analyzed the correlation of the obtained data with others methodologies. The work is divided in three chapters. Chapter 1 pre
