Proteins (from the Greek word protos, meaning first) occur ubiquitously throughout all organisms, where they participate in a wide variety of biological functions. Proteins provide the structural rigidity and flexibility associated with external body parts such as skin, hair, and the exoskeletons of arthropods. By changing their structure they provide the basis for biological motions, such as muscle contraction. A large class of proteins, the enzymes, serve as biological catalysts, enhancing greatly the rates of chemical reactions that are vital to life (Copeland, 1992).
