Magnetic field effects on bistability and bifurcation phenomena in lipid peroxidation.
A simple model based on physically evident assumptions was constructed that may predict the strong effect of low intensity magnetic fields (MFs) on living systems. As a model system, we studied MF effect on lipid peroxidation reaction under steady state conditions. It was assumed that external MF affects rate constants of radical reactions taking place in elementary stages of lipid peroxidation reaction. It was shown that under certain conditions, low intensity MF may provoke a bifurcation transition in the system followed by a significant change in its characteristics. This means that, in principle, an external MF may play a critical role in lipid peroxidation reaction and a cell life.
