Introduction: Protein, as the largest macromolecule in the body, is one of the most important components of living organisms, which plays an important role in these systems. Proteins are composed of amino acid chain sequences. The number of amino acids depending on the type of protein, can reach several thousand. The bioenergy transfer in protein chains is one of the most important topics in biology, which is vital in many processes such as muscle contraction, DNA amplification, neuroelectric pulse transfer on neurolma, calcium and sodium pumps, and so on.
Analysis method: In this work, the bioenergy transfer in protein molecules is studied. In this regard, by considering the laser radiation, the effect of temperature has been investigated. Using the nonlinear dynamical systems theory, the evolution equations of system and energy flux are derived. Also, the effect of temperature and the temperature difference between the two ends of the system is studied.
Results: The energy flux at different time intervals shows some peaks. The sequence with a length of 20, shows the higher peaks than the other two sequences with lengths of 150 and 300. The energy flux with respect to temperature shows some fluctuations. If the temperature of the cold source is kept the constant and the temperature of the hot source changes, the energy flux versus the temperature difference between the hot and cold source changes. On the other hand, by simultaneously variation the temperature of the hot and cold source, we can examine the variation of energy flux with respect to the temperature.
Conclusion: Time variation of energy flux shows the chaotic behavior. By decreasing the sequence length, the energy flowing through the system increases. In the current study, we have studied the effect of temperature due to the laser radiation on the energy flux. We have observed that the energy flux through the system at 345 Kelvin reaches its maximum value. By applying a variable temperature gradient, we conclude that the energy flux increases with decreasing sequence length at the temperatures difference higher than 10 K. By applying a constant temperature gradient, we observed that the energy flux reaches its maximum value when the hot source temperature reaches 345 Kelvin.
