Distribution of macromolecule chain´s conformation

We have built a physical model about macromolecule´s chain conformation by applying the methods of physics, and then we have mainly simulated macromolecule chain´s conformation. We also have studied the single chain system conformation´s size which represented by mean-square end to end distance R2 and mean-square radius of gyration R², shape and the variation of energy which acted between different chain lengths. The results shows that the average energy Ec and the size which represented by mean-square end to end distance R2 and mean-square radius of gyration R² are proportional to the variation of chain´s length. When the chain lengthens, the distribution of chain conformation in a small size area will be expanded and increased. When the chain length reaches from 10 to 16, chain conformations are mostly distributed the area with high energy and small size.
