¦¡-helical Protein Passed The Computer Simulation Of The Bio-energy Solitons

In the living process, matter is basic, bioenergy is central, and bioinformation is pivotal, to which all physiological processes and phenomena are related. Therefore, bioenegy is one of the most important and fundamental problems in the living process.This thesis begins with introduction of the development and investigation situation in the field of bioenergy transfer simply. And then, the theory proposed by Ukrainian scientist A.S.Davydov, called Davydov theory, is put forward. However, the validation and research on it by other scientists reveals that there are some limitations. Thus, the theory has been improving by lots of scientists from various angles. Theoretically, Prof. Xiaofeng Pang did greatly. Thereby, the improved theory proposed by Prof. Pang are expatiated and analyzed in detail. Next, the relevant soliton dynamic equations of bioenergy transfer are worked out. In succession, the equations are transformed and discretized to perform numerical simulation easily. Moreover, by study of the bioenergy transfer through single-chain protein, it makes enough preparation for later formal work. Bioenergy transfer appears in the motor-protein, actin, actomyosin, collagen-protein and so forth, so thatα-helical protein with three-chain becomes the object of study. With the consideration of conditions of the numerical simulation, the parameters and structural characteristics of the protein are adopted accurately.Considering protein commonness and the particular characteristic ofα-helical protein with three-chain in simulation, the problems of bioenergy transfer are investigated more. First, according to the standard parameters ofα-helical protein, by simulating the soliton dynamical equations, the theory has been studying further. Secondly, because protein is a high order, anisotropic and complicated self-organization system, its structure is disorder, that is, the parameters in soliton dynamical equations of the improved theory are various. Hence, by creating a series of alterable parameters through a randomizer for bettering the methods, the influence brought by every parameter's change is observed. Later, all parameters are taken together into account, namely, the influence of disorder structure. Thirdly, the influences of temperature and impurities on dynamic properties should be considered carefully. At last, owing to the fact that protein exist in organism, thus, aforementioned conditions function at the same time and all the while and should be combined to be thought over. In this way, the results could be close to actuality. In every step described above, the conclusions are compared with those of single-chain protein studied in documents and in the preparative work of the thesis. Finally, better conclusions have been achieved than before.
