生物分子激发态及其变化的特性研究

We concluded following important results for the nonlinear excitations and dynamical properties of protein molecules and DNA from their structures and conformation changes by molecular biology and nonlinear quantum theory in this subject of National Natural Science oundation:(1)We proposed and established the new theory of bio-energy transport in the living systems in which lifetimes of the soliton transporting the bio-energy in the protein is about 10－10 sec. In this period the soliton can move over 600-1000 amino acid residnes. Thus we can behave that the soliton is a possible candidate of carrier of bio-energy transport..(2)We proposed and established the new theory of transfer of charged proton or hydrogen ion in the hydrogen-bonded systems including protein molecules, and found out the mobility and conductivity of the hydrogen ion to be (7.6-8.3) 10-3(m· )－1and（6.6-6.9） 10-6(m2/v·sec) in ice crystals or protein molecules hichapproach the experimental data.(3)We gave the new mothod to calculate the vibrational energy-spectra of molecules containing mecrobiomolecules, obtained theirproperties of energy-spectra and opitical features, and exposed the mechanism and features of nonthermally and thermally biological effects of infrared lights. Meanwhile, we exhibit the physical fundamentals of form of o-self-organization and the mechanism and features of bio-photon of visible light..(4)We gave the new model of dynamics of DNA and explained the reproduction and transcription and phase transition for DNA from B-type to A-type and Z-type under externally applied fields and due to the changes of temperature and tconcentration in the systems .(5)We exposed the mechanism and features of eletronic migration in the living system and gave its mobility and the kinetic coefficient. .These results obtained are helpful to expose the mechamisms of muscle contraction and ionic channal on the bio-membranes and light-synthesis reaction in plant, and genetic feature and gene representation. Therefore the research acheviements have importantly academic meaning in life science.
