Through the diagrams of the RMSD value variation curve and corresponding time trajectory sampling of the molecular model, we could see that type I collagen's stability decreased and its structure changed with the temperature rising and it is found that the higher the temperature was, the more apparent the structure changed. For example, RMSD value reached 5A at 380K, conformational space turned to an intermediate folded bending condition which is different from its natural state. Thus, we provided a new and efficient way of researching the natural leather's thermal stability.
