Product formation has been determined and phase purity has been examined by analysis of powder X-ray diﬀraction patterns. Formation of hydrogen-bonded co-crystals is favoured from less polar solvents and halogen-bonded co-crystals from more polar solvents.

WebOur results indicate that a large fraction of the protein solvent accessible surface is polar and that at least 192 residues are involved in protein–protein interactions. Furthermore, we found that some 81 residues are likely to be involved in calcium ion binding, and that they are mainly clustered in the regions where protein–protein interactions do not occur. http://murov.info/orglab/6-e1.pdf
