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 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.

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.
