[57] ABSTRACT

Disclosed are [3-peptides containing cylcoalkyl, cycloalkenyl, and heterocylic substituents Which encompass the (X and [3 carbons of the peptide backbone. The [3-peptides adopt stable helical and sheet structures in both the solid state and in solution. Method of generating combinatorial libraries of peptides containing [3-peptide residues and the libraries formed thereby are disclosed.
