Abstract
The thermodynamic dissociation constants of calcium glucose 1-phosphate were measured at 10[degree] intervals from 10[degree] to 50[degree] by using hydrogen and silver-silver chloride electrodes in cells without liquid junction. From these measurements were calculated the changes in standard free energy, heat content, entropy and heat capacity for the dissociation at 25[degree] and 37[degree]. Sufficient information was given for the dissociation of this salt to be considered quantitatively in any kinetic or other study of glucose 1 -phosphate in the presence of Ca2+ ions.
