Protein Molecule Structures

For 50 years, the “protein folding problem” has been a major mystery. How does a miniature string-like chemical — the protein molecule – encode the functions of living organisms: how our muscles exert force, how our immune systems reject pathogens, how our eyes see our surroundings, how plants convert solar energy, and all the rest. Huge progress is being made. Moreover, these amazing nano-machines could play important roles in health and disease and commerce in the future.
