Consider the binding of a ligand to a protein, for which KD=62.8M. Initially, the concentration of protein is 5.9M and the concentration of ligand is 22.6M. Find the fractional occupancy of the ligand binding sites. Hint: This is an ICE table problem. Start by finding the equilibrium concentrations of all species, then substitute into f=[P]+[PL][PL]. It is possible that you will need the quadratic formula for this
