Raman OD stretching spectra and homogeneous nucleation temperatures (T_H's) were measured for aqueous solutions of sucrose, maltose and trehalose over wide sugar concentration and temperature ranges. Comparison of the Raman and T_H data indicates that there are small differences in Raman spectra and T_H values among the three aqueous saccharide solutions. It is deduced that the high activity of trehalose as a protecting agent against water stress in biological systems may be due to the direct stabilization of the biological structures to be protected.
