Outline of Final Research Achievements

There are many polymers showing LCST-type phase transition behavior under physiological conditions. However, there is few polymers showing UCST-type phase transition behavior under the conditons. We have reported that poly citrulline polypeptide showed UCST-type behavior. In this study, we estimated effect of optical activity of the polypeptide on UCST-type solution behavior. CD spectra indicated that the polypeptide adopted a-helix conformation and form a bundle structure below phase separation temperature.
