| Research Abstract |
Hydration numbers and solvation numbers of typical synthetic and natural polymers like collagen model polypeptides and pullulan were successfully determined in solutions of aqueous and organic media using high frequency dielectric relaxation techniques. Many polymers possessing amide groups show characteristic dehydration behavior, in other words decreasing in the hydration number, around 30℃. Such the kind of dehydration behavior is commonly observed in proteins and also in their monomers, amino acids, and is responsible for the temperature dependence of sizes of proteins in aqueous solutions.
