Abstract: | The mechanism and properties of infrared absorption of α-helix protein molecules are studied by a theory of bio-energy transport
established on the basis of molecular structure. From the vibrational energy-spectra of molecules obtained from this theory
we know that the infrared lights with wavelengths of 2 μm −7 μm can be absorbed by α-helix protein molecules. This is basically
consistent with experimental data of infrared absorption of collagen and hemoglobin and bivine serum albumen (BSA) proteins
with α-helix structure. From these results we account further for the mechanism and properties of biological effect of infrared
lights absorbed by the living systems, i.e., the energy of infrared lights is directly absorbed by the amide-Is in amino acid
residues in the protein molecules, which results in vibration of amide-1 and change of conformation of proteins and transport
of bio-energy from one place to other along the protein molecular chains in human beings and animals. This is a kind of non-thermally
biological effect. |
