The Peptides: Analysis, Synthesis, Biology: Volume 4: Modern Techniques of Conformational, Structural, and Configurational Analysis is an open-ended treatise that provides comprehensive and critical reviews of important developments in all areas of peptide research including analysis, synthesis, and biology. X-ray structure studies, amino acid analysis, and chiroptical analysis of configuration are discussed, along with solid-phase sequencing and ultramicroanalysis with the aid of fluorescence. This volume is comprised of six chapters and begins with an account of crystal structure analysis on molecules containing 2-12 peptide units, focusing on the variety of intramolecular hydrogen bonds, cis peptide units, and multiple conformation. Conformational changes upon complexation with metal ions are considered, together with the inclusion of solvents as integral parts of a molecular structure. The following chapters explore the conformations of insulin, glucagon, pancreatic polypeptide and related molecules, as well as the molecular biology of these hormones based on crystal structures; the usefulness of chiroptical techniques for determining the absolute configuration of amino acids and small peptides; and ultramicroanalysis of peptides and proteins by high performance liquid chromatography and fluorescence detection. The final chapter looks at the status and future potential of solid-phase sequencing. This book is intended as a reference for specialists, a guide for the novice, and a forum for investigators concerned with research on peptides and proteins.

The Peptides: Analysis, Synthesis, Biology, Volume 1: Major Methods of Peptide Bond Formation provides comprehensive and critical reviews of important developments in three major areas of peptide research—analysis, synthesis, and biology. This book discusses the nature of the peptide bond, coupling between amino acid residues, and catalysis of active ester reactions. The formation of hydrazides, reactions of carbodiimides with amines, and mixed carbonic anhydride method of peptide synthesis are also elaborated. This publication likewise covers the control of racemization during peptide synthesis, strategies for minimizing racemization during amide-forming steps, and assays for chiral purity. This volume is suitable for students, specialists, and scientists from a broad range of disciplines concerned with peptides.

The Peptides: Analysis, Synthesis, Biology, Volume 3: Protection of Functional Groups in Peptide Synthesis focuses on protection of functional groups in peptide synthesis. This book consists of seven chapters. Chapter 1 reviews the large variety of amine protecting groups. The protection of carboxyl groups is described in Chapter 2, while the chemistry of sulfhydryl group protection in peptide synthesis is discussed in Chapter 3. Chapter 4 covers the protection of the hydroxyl groups of serine, threonine, tyrosine, and other hydroxyl-containing amino acids. Differential protection and selective deprotection in peptide synthesis is deliberated in Chapter 5. In chapter 6, the opportunities and constraints of the tactics of minimal protection of side-chain functions during peptide synthesis are reviewed. The last chapter is devoted to the interesting aspects of dual function groups. This volume is recommended for specialists and researchers concerned with peptide and protein research.

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 Peptides: Analysis, Synthesis, Biology, Volume 6: Opioid Peptides: Biology, Chemistry, and Genetics presents a biological topic of peptide research. This book is divided into nine chapters. Chapter 1 reviews the opioid peptide precursors and their genes. The proenkephalin and products of its processing are discussed in Chapter 2. In Chapter 3, the role of pro-opiomelanocortin (POMC) as a protein at the interface of the endocrine and nervous systems is examined. Chapter 4 provides a comprehensive account of the biology and chemistry of the dynorphin peptides. The opioid receptors are described in Chapter 5. Chapter 6 evaluates the structure-activity relationships of ?-endorphin, while Chapter 7 considers the conformational analysis of enkephalins and conformation-activity relationships. The structure-activity relationships among enkephalin peptides are elaborated in Chapter 8. The last chapter is devoted to the clinical significance of opioid peptides in humans. This publication is a good reference for biologists, specialists, and researchers concerned with peptides and proteins.
