Abstract

The insertion of additional atoms into \alpha -polypeptide backbones by the introduction of \beta, \gamma, and higher \omega amino acid residues expands the range of polypeptide secondary structures.[1] Two new helices, the $2.5_{1}_{2} ((P)-2.5_1)$ helix and the $3_{1}_{4} ((M)-3_{1})$ helix, were first identified in studies of oligopeptides.
