| 中文摘要 | Temperature and structural disorder can have a strong influence on the stability of solitons excited in protein molecules. This problem has been studied in depth with an improved model, using numerical simulation and the Runge-Kutta method, for biological temperatures. The results obtained show that the soliton is thermally stable in the region of biological temperatures, 300 K < T < 320 K, and is very robust against structural disorder, including substantial disorder in the sequence of masses of the amino acids and fluctuations of the spring constant, coupling constant, dipole-dipole interaction constant and ground state energy, due to its larger binding energy which can suppress the destructive effect of the above types of disorder and thermal perturbation. Therefore this soliton is a possible carrier for bio-energy transport in protein molecules. However, very strong structural disorder can also destroy the stability of this soliton. |
