title: [Helix-forming conformers in structural organization of methylamides of N-acetyl-alpha-L-amino acids. Quantum-chemical study].
abstract: Based on the results of quantum-chemical PM3 calculations, some common structural and thermodynamic properties of low-energy monopeptide conformers have been revealed that may be responsible for the initiation of alpha- or beta-like forms in polypeptide structures.
