Physical Principles and Techniques of Protein Chemistry Part C, Part 3Sydney Leach Physical Principles and Techniques of Protein Chemistry, Part C focuses on the effects of intermolecular interactions that are transmitted between ligands and proteins and from protein to protein. This book discusses the density and volume change measurements; direct volume change; osmotic pressure; and small-angle X-ray scattering. The theory of particulate scattering; pulsed nuclear magnetic resonance; absorption of water by diamagnetic molecules; and use of least squares in data analysis are also elaborated. This text likewise covers the iteration process; optical rotatory dispersion and the main chain conformation of proteins; and basic relations for optically active molecules. Other topics include the circular dichroism, secondary structure of proteins, visible rotatory dispersion, and peptide cotton effects. This publication is intended for protein chemists, but is also useful to biologists, medical practitioners, and students researching on protein chemistry. |
