✦ Synopsis

Although the conformations of two linked peptide units both with glycyl and alanyl residues have been extensively studied,'-$ no systematic investigation of the energies of conformations of two linked peptide units with side chains beyond the CB atom and a comparison with the available crystallographic data appears t o have been made so far, nor are there reports of calculations on the Nand C-terminal residues. Recently we r e ported potential energy calculations on the preferred molecular conformations of glycine, alanine, and aminobutyric acid4,5 and on the backbone conformations of Nand C-ter-
