摘要：

Using 1D and 2D H-1 NMR techniques, conformational analysis of model peptides 1 and 2 revealed that the Thr residue is conformationally restricted to a fully extended C-5-structure, stabilized by an intraresidue hydrogen bond. Systematic investigation provided distinctive H-1 NMR spectral parameters for this conformation across a (CH)-H-alpha bearing chiral proteinogenic residue. (C) 1997 Elsevier Science Ltd.
