Peptides

Peptides covers the proceedings of the Sixth European Peptide Symposium, held in Athens, Greece on September 1963. This symposium brings together numerous works on the synthesis, reactions, biological activity, and physico-chemical properties of peptides. This book is organized into seven sections encompassing 46 chapters. The first three sections describe the methods of peptide synthesis, racemization, and degradation of peptide chains. These sections examine the developments in non-enzymatic selective modification and cleavage of peptides, as well as the oxidative modification of specific peptide chain. The succeeding section highlights the total synthesis of natural peptides and peptide analogues and the evaluation of the structure-activity relationships and biological properties of these peptides. These topics are followed by discussions on the synthetic pathways and properties of certain special peptides, along with the accompanying synthesis problems with uncommon amino acids and abnormal peptides. This final section explores the gas-chromatographic studies on the physic-chemical properties of peptides. This book will prove useful to organic chemists, biochemists, and peptide researchers.
