Oligomers containing both α- and γ-aminoacid residues in a 1:1 alternating pattern have recently been shown by several research groups to adopt helical secondary structures. We have begun to explore the folding behavior of oligomers with different α-residue/γ-residue backbone patterns. Previously we reported that the γ-aminoacids bearing a cyclohexyl constraint at the Cβ–Cγ bond and a variable side
