  In this paper, we mathematically describe the time evolution of protein
folding features via Iori et al.'s heteropolymer model. More specifically, we
identify that the folding amino acid chain evolve according to a power law $D
\sim t^{\nu}$. The power $\nu$ decreases from $0.\overline{66}$ to $0.5$ when
the randomness of the coupling constants in the Lennard-Jones potential
increases.
