Aprotein has two strcutural forms r and t these structural forms are in equilibrium with the equilibrium constant: k=[t]/[r]. also, both t and r each have a single binding site for ligand l and have equilibrium constants: kt=[tl]/[t][l] and kr=[rl]/[r][l].a) for this model the binding polynomial is defined as qb=[r]+[t]+[tl]+[rl]. assume k=10, kt=0.100 and kr=1.00. calculate the value of qb/[r]. assume also [l]=0.1m. assume qb/[r] is dimensionless. b)for the model in part a calculate the binding fraction fb. c)for the model in part a the equilibrium constant between rl and tl is defined as l=[tl]/[rl]. calculate the value of l assuming the model in part a.
