✦ Synopsis

Abstract

Stereochemical studies predict that α‐amino isobutyric acid, one of the amino acids found in antibiotics, can fold only into left‐ or righthanded α‐helical conformations. Such residues will direct chain folding and should be useful in synthetic analogs of protein sequences to increase helix stability.
