9.6 Conclusions
We have described a few generic situations in which electrostatic interactions
between charged macromolecules seem to play an important role. With MC
simulations we can obtain the exact answer within the given interaction model,
which allows us to test the validity of approximate theories. Many biochemical
systems are comparatively weakly charged, in contrast to many inorganic
systems, and so simple theories based on the DH approximation give accurate
answers. The long-range character of the Coulomb interaction often means that
the geometry and detailed distribution of the charged groups are less important
for the interaction of two charged macromolecules.
