【Abstract】 Polypeptide is a kind of polymer synthesized by amino acid and their derivates. Due to their unique structures and properties, synthetic polypeptides recently have been studied widely in the field of protein simulation, macromolecular conformational study and biomedicine. This paper mainly reviews the research and application statues of polypeptides in synthesis, molecular conformational study, liquid crystal phase behavior, self-assembly behavior and drug delivery system. The developing tendency of polypeptides in tissue engineering is also discussed.更多还原
