Amino Acids, Peptides and Proteins in Organic Chemistry, Analysis and Function of Amino Acids and Peptides : Analysis and Function of Amino Acids and Peptides

This is the last of five books in the Amino Acids, Peptides and Proteins in Organic Synthesis series. Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international ""who's who"" in amino acid research, these volumes represent a real benchmark for amino acid chemistry, providing a comprehensive discussion of the occurrence, uses and applications of amino acids and, by extension, their polymeric forms, peptides and proteins.

This is the last of five books in the Amino Acids, Peptides and Proteins in Organic Synthesis series.

Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international "who's who" in amino acid research, these volumes represent a real benchmark for amino acid chemistry, providing a comprehensive discussion of the occurrence, uses and applications of amino acids and, by extension, their polymeric forms, peptides and proteins.

The practical value of each volume is heightened by the inclusion of experimental procedures.

The 5 volumes cover the following topics:

Volume 1: Origins and Synthesis of Amino Acids

Volume 2: Modified Amino Acids, Organocatalysis and Enzymes

Volume 3: Building Blocks, Catalysis and Coupling Chemistry

Volume 4: Protection Reactions, Medicinal Chemistry, Combinatorial Synthesis

Volume 5: Analysis and Function of Amino Acids and Peptides

Volume 5 of this series presents a wealth of methods to analyze amino acids and peptides. Classical approaches are described, such as X-ray analysis, chromatographic methods, NMR, AFM, mass spectrometry and 2D-gel electrophoresis, as well as newer approaches, including Surface Plasmon Resonance and array technologies.

Originally planned as a six volume series, Amino Acids, Peptides and Proteins in Organic Chemistry now completes with five volumes but remains comprehensive in both scope and coverage.

Further information about the 5 Volume Set and purchasing details can be viewed here.
