Abstract: The purpose of this paper is to investigate the length scale effects of small protein folding by lattice modeling. Heat capacity is computed to analyze folding transition temperature of the model proteins of different lengths. The results show that there is an evident phase transition when the lengths of the model proteins are similar to those of foldons. Furthermore, it is found that the folding transition temperature is proportional to the sequence length.
