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.
