Reversible thermo-sensitivity induced from varying the hydrogen bonding between the side residues of rationally designed polypeptides†
Abstract
Rationally designed polypeptides with similar molecular structures but varying patterns of hydrogen bonding between the side groups have been synthesized and demonstrated to possess distinct solubility and thermal behaviors. Further balancing the ratio of both isopropylamine and ethylenediamine side groups endows the random copolymer with reversible thermo-sensitivity.
