Thermodynamics of some nucleic acid bases and nucleosides in water, and their transfer to aqueous glucose and sucrose solutions at 298.15 K.
The partial molar heat capacities and volumes of some of the constituents of nucleic acids have been determined in water and 1 molal aqueous glucose and sucrose solutions in order to elucidate the nature of interactions occurring between various nucleic acid bases, nucleosides and the sugar (glucose and sucrose) molecules. The results have been explained in terms of the contributions from hydrophobic interactions, hydrophilic interactions and the hydrogen bonding between the solute and solvent molecules. The results have also been compared with those of amino acids and peptides in aqueous glucose and sucrose solutions.
