[Effect of amino acids and low molecular weight peptides on the dynamics of water]

The effect of amino acids and low-molecular-weight peptides on the dynamics of water was studied. Water medium together with molecules of dipeptides and amino acids dissolved in it is considered as a complex of interacting anharmonic oscillators. It was shown that the temperature behaviour of this system is determined by nonlinear resonances, which give rise to both the phenomenon of self-synchronization in the whole system or its part and to the phenomena of phase instability and coherence decay, depending on the store of oscillatory energy. Dissolved molecules are also involved in these oscillations, and if the frequencies and amplitudes of their oscillations are within the range in which nonlinear resonance occurs, they can affect the movement of the whole system.
