title: Conformational study of [Leu5]-enkephalin by laser Raman spectroscopy.
abstract: The Raman spectrum of [Leu5]-enkephalin in the solid state indicates the presence of a type I' beta bend, in agreement with X-ray data of Smith & Griffin (1978). In solution, this molecule takes on different conformations in different solvents. In DMSO-d6, it forms a beta-bend structure whereas in water it exists as an ensemble of conformations.
