Fig. 4. Inclusion matrix of Dianin s compound (i) (schematic representation) Individual Dianin molecules are represented by a specified hydroxy group attached to an elUpsoid. The characteristic hydrogen bridge networks are indicated by the shaded hexagons (H-bonds in dotted lines). The hatched sphere in the centre of the cavity pictures an included guest molecule, e.g. chloroform...

The relatively low cooperativity of this ID system has been attributed to the flexibility of the btzp bridging ligand, which may act as a shock absorber against the elastic interactions between active SCO sites, as well as to the absence of a hydrogen bonding network. This compound undergoes the... 

The attachment of the MM to the CP may possibly involve the incorporation of water which would link the two fractions via hydrogen bonds. Sterically, the water would fit perfectly into such a network and a greater stabilization would be achieved. The presence of water in shell structures either within the mineral or associated with the intracrystalline matrix has been reported232). On the other hand, the high amount of serine in the CP could provide the necessary hydrogen bridges. 

As shown in Figure 4 of section 2, the dipeptide molecules are arranged in a parallel / -sheet-like structure which is constructed by ionic pairing of carboxyl and amino groups via a hydrogen bonding network one terminal COO bridged two +NH3... 

Bound solvent molecules are an integral part of the structures of their proteins. This is seen in the extensive hydrogen bond networks that they form and that bridge protein atoms. Such cross-linking is observed internally as well as externally many globular proteins contain a number of buried water molecules. The water molecule is unique because it has both double-donor and double-acceptor capability.
