Nuclear Magnetic Resonance in Polypeptide Liquid Crystals

Abstract

Some twenty years ago it was found that synthetic polypeptides, Open image in new window , can exist as rigid, rodlike α-helical molecules, in contrast with the random coil conformation adopted by most other synthetic polymers in solution. This observation with its implications in the study of protein structure stimulated a concentrated and sustained investigation of the dilute solution (1–5 wt.% polymer) properties of this class of polymers. In more concentrated polypeptide solutions (10–15 wt.% polymer), poly (γ-benzyl-L-glutamate) (PBLG; R = CH2CH2COOCH2C6H5), forms a lyotropic liquid crystal. Robinson1 extensively characterized the PBLG liquid crystal and found similarities between its supra-molecular structure and the structure existing in thermotropic cholesteric liquid crystals.
