WebThe Ka value is the equilibrium constant for the dissociation reaction of the protein-ligand complex, where a higher Ka value indicates a stronger binding affinity between the protein and the ligand. To determine what percentage of the proteins are bound to the ligand, we can use the equilibrium binding equation: WebWell, it says that k0 is binding affinity without a metal, and ka is then the opposite, aka how good it is at binding with a metal. So, if the ratio of Ka : K0 is less than 1, e.g., 9/10 or 1/2, then that means, k0 is higher, meaning better at binding withOUT a metal. 1 More posts from the Mcat community 495 Posted by u/TestAnxietyIsReal 3 days ago
