Description	The densities of hyaluronan solutions in water and 0.15 M NaCl were measured in the temperature range from 25 to 50 C for the hyaluronan molecular weights from 10 to 1750 kDa. The density increased linearly with concentration and decreased with temperature. The data were fitted by the equation describing the density as a linear function of concentration and a quadratic function of temperature. The effect of molecular weight was negligible and thus single equation was sufficient to describe all data. The apparent and partial specific volumes were calculated from the density data including their extrapolated values to infinite dilutions. The measurement of ultrasound speed in the same solutions under the same conditions enabled to calculate the compressibility and its dependence on concentration and temperature. The compressibility decreased with both the concentration and the temperature but the effect of the concentration was only slight mild. The compressibility was used to estimate the hydration num The densities of hyaluronan solutions in water and 0.15 M NaCl were measured in the temperature range from 25 to 50 C for the hyaluronan molecular weights from 10 to 1750 kDa.
