Abstract
The discovery of significance of iron-NADH complexation for the kinetics of NADH decomposition and oxidation led to an investigation of the influence of solution oxygen and biologically prominent metal ions on NADH degradation. Almost all metal ions under investigation appeared to complex quickly with NADH. Studies of kinetics of simultaneous processes of NADH acid-catalyzed decomposition, complexation, and oxidation in different environments were undertaken. It was observed that Fe2+ and Fe3+ were the only solution ions which caused a decrease in NADH decomposition rates, opposite to all other metal ions under investigation. The presence of metal ions accelerated NADH acid-catalyzed decomposition to a greater extent than NADH oxidation. Contrary to most literature sources, it was determined that the second, and not the first step of decomposition is rate-limiting. (Abstract shortened by UMI.).
