PEACH, a program for molecular dynamics simulation of biochemical molecules, was transplanted from UNIX computer to Windows computer. Visual Fortran was utilized as the compiler. MD simulation of two model proteins, glucagon and prion, was performed at several different temperatures. The structures of 1AG2 and 1GCN were used as initial structures for the simulation. The helix-coil transition was observed in a few nano seconds at 400 K in the case of the glucagon model.
