Biophysical Chemistry (tutorial Chemistry Texts)

E-Book Overview

Biophysical Chemistry covers the physical chemistry of biological macromolecules and the experimental techniques used to study them. Topics covered include: an introduction to biological molecules; spectroscopy, mass spectrometry and hydrodynamics of macromolecules; a "bluffer's guide" to molecular thermodynamics; biomolecular kinetics; chromatography and electrophoresis; and single-molecule methods. The easily digestible, pragmatic approach captures the reader with the fascinating challenges the subject poses for theoretical and experimental scientists. This book will be ideal for early undergraduates studying chemical or physical sciences and will act as a basis for more advanced study. Students in other areas of biological sciences will appreciate the less intimidating approach to physical chemistry as demonstrated here. Ideal for the needs of undergraduate chemistry students, Tutorial Chemistry Texts is a major series consisting of short, single topic or modular texts concentrating on the fundamental areas of chemistry taught in undergraduate science courses. Each book provides a concise account of the basic principles underlying a given subject, embodying an independent-learning philosophy and including worked examples.

It is a product of evolution, the outcome of countless random experiments, resulting in the exquisite complexity of the biological world of which we are a part. Setting aside any philosophical considerations, living organisms - including ourselves - are simply nothing more than wet, floppy bags of chemistry: complicated mixtures of molecules interacting in a multitude of ways. All this takes place mainly in water, a solvent that most chemists try to avoid because of its complexities. However, we can learn from this. In the course of evolution, biology has had the opportunity to perform vastly more experiments than we can ever contemplate in the laboratory. The resulting chemistry is fascinating in its own right, and we can quite rightly study it for its intellectual satisfaction alone. We can also, if we choose, apply what we learn to other areas of chemistry and to its applications in biomedical and environmental areas.
