On the possible role of small polarons in the charge and energy transport in the alpha-helix proteins
MetadataShow full item record
We study the possibility of the small-polaron creation in alpha-helix proteins, accounting for the self-trapping of the intramolecular vibration energy quanta. The small-polaron concept of energy transfer in polypeptides has been revisited on the basis of these results. It was found that traditional small-polaron theories cannot be directly applied to the vibrational quanta transfer in these substances. In particular, true eigenstates of system should correspond to a partial dressed polarons rather than to the fully dressed small polaron states.
