As one of the most important families of non-natural poly-mers with the propensity to form well-defined secondary structures, theb-peptides are attracting increasing attention. The compounds incorporatingb-amino acid residues have found various applications in medicinal chemistry and conformational pool ofb-peptides com-prises several periodic folded conformations, which can be classified as helices, and nonpolar and polar latter two are prone to form pleated numerous studies that have been performed on the side-chain dependence of the stability of the folded structures allow certain conclusions concerning the principles of design of the b-peptide foldamers
