Kinetics of the reaction of phosphoenol pyruvic acid with tetranitrosyl iron complex with penicylamine ligands – nitrogen monoxide donor

The kinetic patterns of the reaction of phosphoenolpyruvic acid (PEP) with the NO donor – nitrosyl iron complex with penicillamine ligands (PEN) were studied using mass spectrometric analysis. It has been established that the PEP molecule in an aqueous solution interacts with PEN. The kinetic curves demonstrate the complex multi-stage nature of the reaction. A kinetic model of the process is proposed that quantitatively describes the experimental data.
