Physical Principles and Techniques of Protein Chemistry, Part 2Sydney J. Leach, Sidney J. Leach Physical Principles and Techniques of Protein Chemistry, Part B deals with the theories and application of selected physical methods in protein chemistry evaluation. This book is divided into seven chapters that cover the ultracentrifugal analysis, light scattering, infrared (IR) methods, nuclear magnetic resonance (NMR) spectroscopy, and differential thermal analysis of protein properties. This text first describes the fundamental ideas and methodology of sedimentation analysis of ideal noninteracting solutes and the problems of nonideality and solute-solute interaction. This book then deals ... |
