The Weak Hydrogen Bond



Oxford University Press

The structure and function of biological molecules is to a large degree determined by hydrogen bonding. This is the case for proteins, nucleic acids, carbohydrates, membranes and also the aqueous medium in which these components are held. The three-dimensional architecture of proteins and nucleic acids is stabilised by hydrogen bonds, biological recognition operates mainly by this mechanism, and the molecular mobility required for biological processes is directly connected with rapid formation and breaking of hydrogen bonds. This chapter discusses the weak hydrogen bond in biological structures, the crystal structures of biological molecules, problems associated with determining the crystallographic resolution problem, and weak hydrogen bonding in peptides and proteins, nucleic acids, carbohydrates, and water molecules.

Keywords:   biological molecules, crystal structures, crystallographic resolution, proteins, peptides, nucleic acids, carbohydrates, water molecules
