Description

Conformation in Fibrous Proteins: And Related Synthetic Polypeptides provides a comprehensive and critical account of conformation in fibrous proteins and synthetic polypeptides in the solid state. Physical methods of determining conformation are discussed, and relevant results from studies of synthetic polypeptides and fibrous proteins are presented. Comprised of 18 chapters divided into three sections, this book opens with a discussion on the theory and technique of X-ray diffraction applicable to the study of conformation in fibrous materials, along with electron diffraction, electron microscopy, optical diffraction, and infrared spectrophotometry. The procedures used for conformation analysis and prediction are also outlined. The following chapters consider optimization techniques and other methods for elucidating conformation in fibrous proteins and synthetic polypeptides; the use of synthetic polypeptides as models of fibrous proteins; and conformation in fibrous proteins such as silks, collagens, myofibrillar proteins, and keratins. This monograph will be a valuable source of information for molecular biologists.
