Resonance Effects of Microwaves are Caused by their Interaction with Solitons in A-Helical Proteins

Abstract

The frequency-dependent, resonance-type biological effects of electromagnetic radiation on a-helical protein macromolecules were treated in terms of Davydov soliton (DS) theory. We studied DS over the temperature range from 0 to 350 K. An important characteristic of the autolocalized state is the bond energy, which defines the soliton stability. As the DSs are stable, only a small probability exists of their energy dissipation into heat providing for the high efficiency of energy and charge transduction in bio-systems. However, under the influence of electromagnetic radiation (EMR), the DS decay (photodissociation) probability increases. This approach allows for the qualitative explanation of the resonant effects of low-intensity microwaves on living organisms found in a number of experiments. The dependence of resonance frequency on temperature was obtained this way. The direct charge transfer along the protein molecule may result from the capture of an extra electron by the moving acoustic soliton (electrosoliton). Decay of the electrosoliton under the influence of EMR (photodisintegration) is also examined.
