The new Second Edition incorporates the significant improvements in the field such as advances in interpreting observed kinetic data, the development of technology to observe fast folding reactions, the molten globule state, and the vital role of chaperone proteins in protein folding. The emphasis on experimental approaches has been maintained but this edition does so within the explicit context of simulations and energy surfaces. New discoveries of the central importance of protein folding and unfolding reactions in biology and medicine (including mutation and 'misfolding') are carefully explored. Three case studies elucidate the difficulties of studying protein folding in vivo.
