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 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.

Human cells produce at least 30,000 different proteins. Each has a specific function characterized by a unique sequence and native conformation that allows it to perform that function. While research in this post-genomic era has created a deluge of invaluable information, the field has lacked for an authoritative introductory text needed to inform researchers and students in all of those fields now concerned with protein research. Introduction to Peptides and Proteins brings together some of the most respected researchers in protein science to present a remarkably coherent introduction to modern peptide and protein chemistry. The first sections of the book delve into – Basic peptide and protein science from assembly through degradation Traditional and emerging research methods including those used in bioinformatics and proteomics New computational approaches and algorithms used to find patterns in the vast data collected by sequencing projects After providing a foundation in tools and methods, the authors closely examine six protein families, including representative classes such as enzymes, cell-surface receptors, antibodies, fibrous proteins, and bioactive peptide classes. They concentrate on biochemical mechanisms and where possible indicate therapeutic or biotechnical possibilities. Then focusing on clinical aspects, the authors investigate misfolding as found in prion diseases, miscleavage as found in Alzheimer’s, and mis-sequencing as found with some cancers. Drawing from some of their own research, the authors summarize recent achievements and emerging applications. They discuss the use of proteins and peptides as drugs and the solid-phase synthesis required for drug production. They also look at the use of peptides as functional biomolecules and research tools. No longer just the domain of biologists, many key advances in protein research started in physics labs and have involved contributions from a host of fields including statistics, drug development, genetics, and chemical spectroscopy. Introduction to Peptides and Proteins provides researchers across these fields with the thorough foundation needed to explore all the potential that protein research offers.

This book presents an overview of antimicrobial peptides (AMPs), their mechanisms of antimicrobial action, other activities, and various problems that must still be overcome regarding their clinical application. Divided into four major parts, the book begins with a general overview of AMPs (Part I), and subsequently discusses the various mechanisms of antimicrobial action and methods for researching them (Part 2). It then addresses a range of activities other than antimicrobial action, such as cell penetration, antisepsis, anticancer, and immunomodulatory activities (Part 3), and explores the prospects of clinical application from various standpoints such as the selective toxicity, design, and discovery of AMPs (Part 4). A huge number of AMPs have been discovered in plants, insects, and vertebrates including humans, and constitute host defense systems against invading pathogenic microorganisms. Consequently, many attempts have been made to utilize AMPs as antibiotics. AMPs could help to solve the urgent problem of drug-resistant bacteria, and are also promising with regard to sepsis and cancer therapy. Gathering a wealth of information, this book will be a bible for all those seeking to develop antibiotics, anti-sepsis, or anticancer agents based on AMPs.
