Apparent helix-coil transition for poly (L-alanine) as measured by nuclear magnetic resonance.

M Goodman, F Toda, N Ueyama.   

Abstract

The previous contention by several groups that double peaks that arise in NMR spectra from NH and alpha-CH protons of poly L-alanines are caused by the coexistence of helical and random-coil structures in solution is disputed.
