Hexanoic acid was added to an immiscible biphasic solvent sysem, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D1) of hexanoic acid in CCl4 with respect to water.
3 a) Scatchard analysis rearranges the basic equation for protein-ligand binding to enable a linear fit of experimental data for bound to free ligand concentration ([L]bound/[L]free) as a function of bound ligand concentration ([L]bound). This enables extraction of the dissociation constant KD and the total protein concentration, [P]total, from the plot. Given the standard equation for a line, y = mx + b, where x is the abscissa and y is the ordinate, express KD in terms of the fitting parameters m and b.
