Details: Product Description
Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.
Review
A highly readable, concise and up-to-date overview of the exciting, vibrant and rapidly growing field of anion coordination chemistry. As world leading practitioners in the area, the authors' enthusiasm for the subject matter comes across loud and clear. ―

CHAPTER 1
Introduction

1.1 Importance of Anions in the Modern World
Although often overlooked in terms of their importance, anions are ubiquitous in the natural world. Chloride anions are present in large quantities in the oceans; nitrate and sulfate are present in acid rain; and carbonates are key constituents of biomineralized materials. Anthropogenic anions, including pertechnetate, a radioactive product of nuclear fuel reprocessing, and phosphate and nitrates from agriculture and other human activities, constitute major pollution hazards.
Anions are also critical to the maintenance of life as we know it. Indeed, without exaggeration, the recognition, transport, or transformation of anions is involved at some level in almost every conceivable biochemical operation. It is essential in the formation of the majority of enzyme–substrate and enzyme–cofactor complexes as well as in the interaction between proteins and RNA or DNA. ATP, phosphocreatine, and other high-energy anionic phosphate derivatives are at the centre of power processes as diverse and important as biosynthesis, molecular transport, and muscle contraction. They also serve as the energy currency for a host of enzymatic transformations. Anion channels and carriers are involved in the transport of small anions such as chloride, phosphate, and sulfate and thus serve to regulate the flux of key metabolites into and out of cells while maintaining osmotic balance.
On a less salubrious level, mis-regulation of various anion transport mechanisms can have serious consequences. For instance, a malfun
