Artificial beta-sheets: chemical models of beta-sheets.

Chemical models provide tools with which to simplify and study complicated biological systems. Forces and chemical processes that govern the structure, function, and interactions of a biomacromolecule can be explored with a simple, easy-to-study synthetic molecule. Chemical models of beta-sheet structures have helped to elucidate the factors influencing protein structures and functions. Chemical models that mimic beta-sheet quaternary structure and interactions are emerging as valuable tools with which to better understand and control protein recognition and protein aggregation.
