The Peptides: Analysis, Synthesis, Biology, Volume 7: Conformation in Biology and Drug Design focuses on the analysis of peptides, emphasizing the use of physical methods in peptide conformational analysis and the relationship of conformational properties of peptides to biological properties. This book consists of nine chapters. Chapter 1 provides a brief overview of the perspective on the application of physical methods to peptide conformational analysis. The use of circular dichroism (CD) spectroscopy to examine the conformational properties of peptides in solution is elaborated in Chapter 2, while the use of fluorescence spectroscopy to examine the special relationships of aromatic side-chain groups to one another is discussed in Chapter 3. In Chapter 4, the use of various theoretical methods to calculate the conformations of peptides is described. The methods used to stimulate peptide conformations and dynamics are outlined in Chapter 5. The last four chapters examine various aspects of the use of nuclear magnetic resonance (NMR) in peptide conformational analysis. This volume is suitable for biologists, specialists, and researchers interested in peptides and proteins.

The application to Biology of the methodologies developed in Physics is attracting an increasing interest from the scientific community. It has led to the emergence of a new interdisciplinary field, called Physical Biology, with the aim of reaching a better understanding of the biological mechanisms at molecular and cellular levels. Statistical Mechanics in particular plays an important role in the development of this new field. For this reason, the XXth session of the famous Sitges Conference on Statistical Physics was dedicated to "Physical Biology: from Molecular Interactions to Cellular Behavior". As is by now tradition, a number of lectures were subsequently selected, expanded and updated for publication as lecture notes, so as to provide both a state-of-the-art introduction and overview to a number of subjects of broader interest and to favor the interchange and cross-fertilization of ideas between biologists and physicists. The present volume focuses on three main subtopics (biological water, protein solutions as well as transport and replication), presenting for each of them the on-going debates on recent results. The role of water in biological processes, the mechanisms of protein folding, the phases and cooperative effects in biological solutions, the thermodynamic description of replication, transport and neural activity, all are subjects that are revised in this volume, based on new experiments and new theoretical interpretations.

Physical Principles and Techniques of Protein Chemistry, Part C focuses on the effects of intermolecular interactions that are transmitted between ligands and proteins and from protein to protein. This book discusses the density and volume change measurements; direct volume change; osmotic pressure; and small-angle X-ray scattering. The theory of particulate scattering; pulsed nuclear magnetic resonance; absorption of water by diamagnetic molecules; and use of least squares in data analysis are also elaborated. This text likewise covers the iteration process; optical rotatory dispersion and the main chain conformation of proteins; and basic relations for optically active molecules. Other topics include the circular dichroism, secondary structure of proteins, visible rotatory dispersion, and peptide cotton effects. This publication is intended for protein chemists, but is also useful to biologists, medical practitioners, and students researching on protein chemistry.

As the tools and techniques of structural biophysics assume greater roles in biological research and a range of application areas, learning how proteins behave becomes crucial to understanding their connection to the most basic and important aspects of life. With more than 350 color images throughout, Introduction to Proteins: Structure, Function, and Motion presents a unified, in-depth treatment of the relationship between the structure, dynamics, and function of proteins. Taking a structural–biophysical approach, the authors discuss the molecular interactions and thermodynamic changes that transpire in these highly complex molecules. The text incorporates various biochemical, physical, functional, and medical aspects. It covers different levels of protein structure, current methods for structure determination, energetics of protein structure, protein folding and folded state dynamics, and the functions of intrinsically unstructured proteins. The authors also clarify the structure–function relationship of proteins by presenting the principles of protein action in the form of guidelines. This comprehensive, color book uses numerous proteins as examples to illustrate the topics and principles and to show how proteins can be analyzed in multiple ways. It refers to many everyday applications of proteins and enzymes in medical disorders, drugs, toxins, chemical warfare, and animal behavior.

Proteins, Pep tides and Amino Acids SourceBook is the second in a series of reference books conceived to cover the explosive growth in commercially available biological reagents. The success of our first reference work, Source Book of Enzymes published in 1997, encouraged us to continue this series. Choosing proteins, peptides, and amino acids as the subject matter for the second volume was simple, given their preeminence in regulating biochemical processes and their importance to modern molecular biology. The SourceBook series was inspired by our difficulty in locating a suitable replacement for a depleted reagent in the midst of an urgent research project. To our dismay, we found the reagent supplier out of business and the product line no longer available. Other reagent catalogs on our library bookshelf offered a narrow selection and incom plete functional information. We were ultimately able to locate a satisfactory alternative only by making countless inquiries and paging through innumerable product catalogs and technical data sheets. We needed-but could not find-a single resource that cataloged available compounds, organized them in a logical and accessible format, provided critical technical information to distinguish one from another, and told us where we could buy them.
