Protein$\alpha$-helices provide an ordered biological environment that is conducive to soliton-assisted energy transport. The nonlinear interaction between amide I excitons and phonon deformations induced in the hydrogen-bonded lattice of peptide groups leads self-trapping energy, thereby creating a localized quasiparticle (soliton) persists at zero temperature. presence thermal noise, however, could destabilize protein soliton dissipate its within finite lifetime. In this work, we have computationally solved system stochastic differential equations govern quantum dynamics solitons physiological temperature, T=310 K, for either single isolated $\alpha$-helix spine hydrogen bonded or full comprised three parallel spines. simulated revealed although noise detrimental spine, cooperative action exciton quanta ensures lifetime over 30 ps, during which be transported along entire extent 18-nm-long $\alpha$-helix. Thus, macromolecular complexes, are built up $\alpha$-helices harness transport Because hydrolysis adenosine triphosphate molecule able initiate quanta, it feasible multiquantal subserve variety specialized functions living systems.
