Hydrogen bonding diamine, diol mixtures

Hydrogen bonding in (Continued diamine, diol mixtures, 138 ethanolamine, 282 nucleic acids, 137-138 proteins, 137-138 water dimer, 138 water trimer, 139... 

This hydrogen-bond-driven large-scale structural organization has parallels in abiotic systems as well. For example, 1 1 mixtures of ra -l,2-diaminocyclohexane and C2 symmetric 1,2-diols self-assemble into well-defined supramolecular structures which have been characterized by X-ray diffraction analysis. The structures, some of which are stable to sublimation, are helical, the handedness of the helices being determined by the handedness of the 1,2-diamine [222].
