This book discusses the chemistry of food proteins and peptides and their relationship with nutritional, functional, and health applications. Bringing together authorities in the field, it provides a comprehensive discussion focused on fundamental chemistries and mechanisms underpinning the structure-function relationships of food proteins and peptides. The functional and bioactive properties hinge on their structural features such as amino acid sequence, molecular size, hydrophobicity, hydrophilicity, and net charges. The book includes coverage of advances in the nutritional and health applications of protein and peptide modifications; novel applications of food proteins and peptides in the development of edible functional biomaterials; advances in the use of proteomics and peptidomics for food proteins and peptide analysis (foodomics); and the relevance of food protein and peptide chemistries in policy and regulation. Research into the fundamental chemistries behind the functional, health and nutritional benefits is burgeoning and has gained the interest of scientists, the industry, regulatory agencies, and consumers. This book fills the knowledge gap providing an excellent source of information for researchers, instructors, students, food and nutrition industry, and policy makers.

Almost two centuries ago proteins were recognized as the primary materials (proteios = primary) oflife, but the significance and wide role of peptides (from pepsis = digestion) in practically all life pro cesses has only become apparent in the last few decades. Biologi cally active peptides are now being discovered at rapid intervals in the brain and in other organs including the heart, in the skin of amphibians and many other tissues. Peptides and peptide-like compounds are found among toxins and antibiotics. It is unlikely that this process, an almost explosive broadening of the field, will come to a sudden halt. By now it is obvious that Nature has used the combination of a small to moderate number of amino acids to generate a great variety of agonists with specific and often highly sophisticated functions. Thus, peptide chemistry must be regarded as a discipline in its own right, a major branch of biochemistry, fairly separate from the chemistry of proteins. Because of the important role played by synthesis both in the study and in the practical preparation of peptides, their area can be considered as belonging to bio-organic chemistry as well. The already overwhelming and still increasing body of know ledge renders an account of the history of peptide chemistry more and more difficult. It appears therefore timely to look back, to take stock and to recall the important stages in the development of a new discipline.

This is the last of five books in the Amino Acids, Peptidesand Proteins in Organic Synthesis series. Closing a gap in the literature, this is the only series tocover this important topic in organic and biochemistry. Drawingupon the combined expertise of the international "who's who" inamino acid research, these volumes represent a real benchmark foramino acid chemistry, providing a comprehensive discussion of theoccurrence, uses and applications of amino acids and, by extension,their polymeric forms, peptides and proteins. The practical value of each volume is heightened by theinclusion of experimental procedures. The 5 volumes cover the following topics: Volume 1: Origins and Synthesis of Amino Acids Volume 2: Modified Amino Acids, Organocatalysis and Enzymes Volume 3: Building Blocks, Catalysis and Coupling Chemistry Volume 4: Protection Reactions, Medicinal Chemistry,Combinatorial Synthesis Volume 5: Analysis and Function of Amino Acids and Peptides Volume 5 of this series presents a wealth of methods to analyzeamino acids and peptides. Classical approaches are described, suchas X-ray analysis, chromatographic methods, NMR, AFM, massspectrometry and 2D-gel electrophoresis, as well as newerapproaches, including Surface Plasmon Resonance and arraytechnologies. Originally planned as a six volume series, Amino Acids,Peptides and Proteins in Organic Chemistry now completes withfive volumes but remains comprehensive in both scope andcoverage. ahref="http://eu.wiley.com/WileyCDA/WileyTitle/productCd-3527335463.html"Furtherinformation about the 5 Volume Set and purchasing details can beviewed here./a

G protein-coupled receptors (GPCRs) are the largest family of cell-surface receptors, with more than 800 members identified thus far in the human genome. They regulate the function of most cells in the body, and represent approximately 3% of the genes in the human genome. These receptors respond to a wide variety of structurally diverse ligands, ranging from small molecules, such as biogenic amines, nucleotides and ions, to lipids, peptides, proteins, and even light. Ligands (agonists and antagonists) acting on GPCRs are important in the treatment of numerous diseases, including cardiovascular and mental disorders, retinal degeneration, cancer, and AIDS. It is estimated that these receptors represent about one third of the actual identified targets of clinically used drugs. The determination of rhodopsin crystal structure and, more recently, of opsin, 1 and 2 adrenergic and A2A adenosine receptors provides both academia and industry with extremely valuable data for a better understanding of the molecular determinants of receptor function and a more reliable rationale for drug design. GPCR structure and function constitutes a hot topic. The book, which lies between the fields of chemical biology, molecular pharmacology and medicinal chemistry, is divided into three parts. The first part considers what receptor structures tell us about the mechanism of receptor activation. Part II focuses on receptor function. It discusses what the data from biophysical and mutational studies, and the analysis of the interactions of the receptor with ligands and regulator proteins, tell us about the process of signal transduction. The final part, on modelling and simulation, details new insights on the link between structure and mechanism and their implications in drug design.

Organic chemists working on the synthesis of natural products have long found a special challenge in the preparation of peptides and proteins. However, more reliable, more efficient synthetic preparation methods have been developed in recent years. This reference evaluates the most important synthesis methods available today, and also considers methods that show promise for future applications. This text describes the state of the art in efficient synthetic methods for the synthesis of both natural and artificial large peptide and protein molecules. Subjects include an introduction to basic topics, linear solid-phase synthesis of peptides, peptide synthesis in solution, convergent solid-phase synthesis, methods for the synthesis of branched peptides, formation of disulfide bridges, and more. The book emphasizes strategies and tactics that must be considered for the successful synthesis of peptides.
