This unique book presents a systematic review of the methods for the determination of binding constants of complex formation in solution. Collects material that has been scattered throughout the literature of several separate fields. Offered here are methods from the areas of acid-base chemistry, metal-ion coordination compounds, hydrogen-bonding, charge-transfer complexation, hydrophobic interaction, and protein-binding. Discusses the relevant thermodynamics, modelling, statistics and regression analysis, and interpretation of data. Includes fresh discussions of random association (contact complexes), selection of standard states, and comparison of results. Treats all of the experimental methods useful for measuring these equilibrium constants, including those based on spectrophotometry, nuclear magnetic resonance, reaction kinetics, potentiometry, solubility, liquid-liquid partitioning, dialysis, chromatography, flourimetry, and many others.

This book describes potentiometric methods for determining stability constants and explains how these constants can be used to describe metal ion speciation in complex environmental and biological systems. It also provides three original computer programs on a disk for calculating stability constants and for using stability constants to calculate concentrations of molecular species in solution. The author gives examples of calculations for simple metal chelates, for metal complexes of large organic molecules, and for mixtures containing several metal ions and complexing agents in aqueous solution. They also describe common errors in calculating stability constants and how to avoid them. This carefully revised second edition is now even more useful to the reader, and, in particular, to those who make use of the program disk. Each program has been revised to improve speed, control, and error trapping.

The second edition of "Analytical Methods in Supramolecular Chemistry" comes in two volumes and covers a broad range of modern methods and techniques now used for investigating supramolecular systems, e. g. NMR spectroscopy, mass spectrometry, extraction methods, crystallography, single molecule spectroscopy, electrochemisty, and many more. In this second edition, tutorial inserts have been introduced, making the book also suitable as supplementary reading for courses on supramolecular chemistry. All chapters have been revised and updated and four new chapters have been added. A must-have handbook for Organic and Analytical Chemists, Spectroscopists, Materials Scientists, and Ph.D. Students in Chemistry. From reviews of the first edition: "This timely book should have its place in laboratories dealing with supramolecular objects. It will be a source of reference for graduate students and more experienced researchers and could induce new ideas on the use of techniques other than those usually used in the laboratory." Journal of the American Chemical Society (2008) VOL. 130, NO. 1 doi: 10.1021/ja0769649 "The book as a whole or single chapters will stimulate the reader to widen his horizon in chemistry and will help him to have new ideas in his research." Anal Bioanal Chem (2007) 389:2039-2040 DOI: 10.1007/s00216-007-1677-1

The binding of small ligands to biological molecules is central to most aspects of biological function. The past twenty years has seen the development of an increasing armoury of biophysical methods that not only detect such binding, but also provide varying degrees of information about the kinetics, thermodynamics and structural aspects of the process. These methods have received increasing attention with the growth in more rational approaches to drug discovery and design. This book reviews the latest advances in the application of biophysics to the study of ligand binding. It provides a complete overview of current techniques to identify ligands, characterise their binding sites and understand their binding mechanisms. Particular emphasis is given to the combined use of different techniques and their relative strengths and weaknesses. Consistency in the way each technique is described makes it easy for readers to select the most suitable protocol for their research. The introduction explains why some techniques are more suitable than others and emphasizes the possible synergies between them. The following chapters, all written by a specialist in the particular technique, focus on each method individually. The book finishes by describing how several complimentary techniques can be used together for maximum effectiveness. This book is suitable for biomolecular scientists at graduate or post-doctoral level in academia and industry. Biologists and chemists will also find it a useful introduction to the techniques available.

A comprehensive reference text explores the nature of chelating agents and the underlying reasons for their metal-binding properties and discusses the mechanisms of absorption for various metals and the possible role of chelating agents in influencing the utilization of certain minerals. Topics include: the physico-chemical characteristics of chelates and chelation and their measurements; the bioavailability of metals and proteins as ligands; the role of phytic acid and other phosphates as chelating agents; miscellaneous chelates (oxalic acid, ionophores, clays); the chelation, uptake, and transport of zinc, and the influence of various foods and synthetic chelates on zinc availability; the chelation, and bioavailability of iron, and the effect of various chelating agents on nonheme iron absorption; chelation of copper by food substances; the chelation of miscellaneous minerals; the role of iron and copper chelation in reproduction; chelate toxicity; the use chelates in metal detoxification and therapy; and the use of chelates for removing metals from dietary ingredients. Technical data and illustrations are presented throughout the text, and reference citations are appended to each of the 12 principal text chapters
