Figure 2.
Densities of aqueous osmolytes at 25oC. Thin dashed lines represent density versus molarity. (A) Density for GPC. (B) Density for taurine and myo-inositol. Parameters of a fit to Eq. 1 are given in Table 1. Densities of saturated solutions (equilibrium supernatants over osmolyte crystals) are indicated in black. The solubilities of taurine and myo-inositol are 806 mmol/kg = 760 mM and 943 mmol/kg = 858 mM, respectively. Also shown is the density of scyllo-inositol solutions. The partial molar volume is 101 mL/mol, and the solubility is 101 mmol/kg = 99.7 mM. To see this figure in color, go online.
