Abstract

This chapter introduces the structural, physical, and chemical foundations of molecular biophysics. The section on structure describes the major molecular components of the cell (water, metabolites, and macromolecules) and discusses the three-dimensional macromolecular structure, folding, and assembly of macromolecules. The section on molecular thermodynamics and kinetics includes energies, equilibria, and rate constants. These concepts are applied to protein folding and aggregation and illustrated with examples relevant to the development of protein pharmaceutics. The chapter closes with a discussion of the interplay between molecular structure and energetics and biological function.
