In solutions with different compositions, tryptophane is surrounded by water molecules alone. This result is in agreement with the known fact of microseparatton of aqueous DMSO solutions. Evidently, in a water-DMSO system, the tryptophane molecules are built into water microregions, in which they have a pure aqueous environment and are thus isolated from the nonelectrolyte present in the solution.
