Abstract:
We here proposed a new theory of bio-energy transport along protein molecules in
living systems based on the changes of structure and conformation of molecules arising
from the energy, which is released by hydrolysis of adenosine triphosphate (ATP). In this
theory, the Davydov’s Hamiltonian and wave function of the systems are simultaneously
improved and extended. A new interaction have been added into the original
Hamiltonian. The original wave function of the excitation state of single particles have
been replaced by a new wave function of two-quanta quasicoherent state. In such a case,
bio-energy is carried and transported by the new soliton along protein molecular chains.
The soliton is formed through self- trapping of two excitons interacting amino acid
residues. The exciton is generated by vibrations of amide-I (C=O stretching) arising from
the energy of hydrolysis of ATP. The properties of the soliton are extensively studied by
analytical method and its lifetime for a wide ranges of parameter values relevant to
protein molecules is calculated using the nonlinear quantum perturbation theory. The
lifetime of the new soliton at the biological temperature 300K is enough large and
belongs to the order of 10-10 second orτ/τ0≥700. The different properties of the new
soliton are further studied. The results show that the new soliton in the new model is a
better carrier of bio-energy transport and it can play an important role in biological
processes. This model is a candidate of the bio-energy transport mechanism in protein
molecules.
