Abstract
The excess thermodynamic properties of aqueous solutions of l-fucose and l-rhamnose have been determined by means of microcalorimetry and isopiestic gravimetry. The data suggest that solute-solute interactions are unfavoured in binary solutions of these hydrophilic compounds, the solute-solvent interactions being predominant. These results lead to the conclusion that the specific function that the corresponding monomeric units seem to have, in some cases, in the reciprocal recognition of polysaccharide chains requires the presence of complexing ions (e.g., Ca2+) and/or specific conformations of the segments of the chains involved in the process. © 1981.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
