A THEORY OF CONFORMATION ELECTRON FIELD
|
Abstract:
Starting from the main variables of biological macromolecules in life processes, the conformations of macromolecules and their frontier electrons, theconcept of interacting conformation--electron field is proposed. Using theformalism of Green function,the elementary excitation of the system of biological macro-molecules is deduced which is a new type of excitation in the sense of anharmonicity and locality. Utilizing the adiabatic conformation electron wave functions the Hamiltonian for conformation transition is deduced. The the -ory is used to investigate doner--acceptor transitions and especially the photon--induced conformation electron transitions. The cooperativity of polymericchains is discussed in the spirit of conformation electron field. The partition function is deduced which generalizes the Ising model and the cooperativity model of Monod et al. The meaning of vibration excitations in cooperative effect is emphasized
