Stereochemical analysis of the secondary structure of polypeptide chains with the aid of Courtauld three-dimensional models. II. Hydrogen and hydrophobic bonds.
Sterically permissible hydrogen bonds between side chains and the backbone, which fix a small number of angles of internal rotation have been identified. The hydrogen bonds on the ends and within the secondary structures, as well as the most important bonds in the alpha helix and in irregular structures, have been considered.
