At equilibrium, the concentrations of reactants and products do not change. But the forward and reverse reactions have not stopped - they are still going on, and at the same rate as each other.

Protein molecules in solution exist as an equilibrium of different conformations, but the sizes and shifts of these populations cannot be determined from static structures. A report now shows how they ...
