  1. ‹∆Evdw› and ‹∆Eele› - van der Waals and electrostatic contributions to binding energy.
  2. ‹∆Gpb› and ‹∆Gnp› - electrostatic and nonpolar contributions to the solvation free energy.
  3. ‹∆GMMPBSA› - final calculated MM-PBSA binding energy.
  4. Nonpolar contribution = ∆Evdw + ∆Gnp; polar contribution = ∆Eele + ∆Gpb.
