The objective of this book is to provide a unifying approach to the study of biophysical chemistry for the advanced undergraduate who has had a year of physics, organic chem istry, calculus, and biology. This book began as a revised edition of Biophysical Chemistry: Molecules to Membranes, which Elizabeth Simons and I coauthored. That short volume was written in an attempt to provide a concise text for a one-semester course in biophysical chemistry at the graduate level. The experience of teaching biophysical chemistry to bi ologically oriented students over the last decade has made it clear that the subject requires a more fundamental text that unifies the many threads of modem science: physics, chem istry, biology, mathematics, and statistics. This book represents that effort. This volume is not a treatment of modem biophysical chemistry with its rich history and many contro versies, although a book on that topic is also needed. The Physical Basis of Biochemistry is an introduction to the philosophy and practice of an interdisciplinary field in which biological systems are explored using the quantitative perspective of the physical scientist. I have three primary objectives in this volume: one, to provide a unifying picture of the interdisciplinary threads from which the tapestry of biophysical studies is woven; two, to provide an insight into the power of the modeling approach to scientific investigation; and three, to communicate a sense of excitement for the activity and wholesome argument that characterize this field of study.

It is highly probable that the ability to distinguish between living and nonliving objects was already well developed in early prehuman animals. Cognizance of the difference between these two classes of objects, long a part of human knowledge, led naturally to the division of science into two categories: physics and chemistry on the one hand and biology on the other. So deep was this belief in the separateness of physics and biology that, as late as the early nineteenth century, many biologists still believed in vitalism, according to which living phenomena fall outside the confines of the laws of physics. It was not until the middle of the nineteenth century that Carl Ludwig, Hermann von Helmholz, Emil DuBois-Reymond, and Ernst von Briicke inaugurated a physicochem ical approach to physiology in which it was recognized clearly that one set of laws must govern the properties and behavior of all matter, living and nonliving . . The task of a biologist is like trying to solve a gigantic multidimensional crossword fill in the right physical concepts at the right places. The biologist depends on puzzle: to the maturation of the science of physics much as the crossword solver depends on a large and correct vocabulary. The solver of crossword puzzles needs not just a good vocabulary but a special vocabulary. Words like inee and oke are vitally useful to him but are not part of the vocabulary of an English professor.

This rigorous, but not overly mathematical, account of the physical principles of modern organic chemistry provides an in-depth treatment of the subject not found in general physical or organic chemistry texts. The author integrates worked numerical examples throughout as well as including them at the end of each chapter. It is appropriate for courses in physical organic chemistry and physical biochemistry at the upper-division and graduate level.
"As will be seen, there is not much missing here. I thought that the sections were well balanced, with rarely too much or too little on a given topic...This is a text to be welcomed by both teachers and students." BIOCHEMISTRY & MOLECULAR BIOLOGY EDUCATION (on the first edition) The second edition of this successful textbook explains the basic principles behind the key techniques currently used in the modern biochemical laboratory and describes the pros and cons of each technique and compares one to another. It is non-mathematical, comprehensive and approachable for students who are not physical chemists. A major update of this comprehensive, accessible introduction to physical biochemistry. Includes two new chapters on proteomics and bioinformatics. Introduces experimental approaches with a minimum of mathematics and numerous practical examples. Provides a bibliography at the end of each chapter. Written by an author with many years teaching and research experience, this text is a must-have for students of biochemistry, biophysics, molecular and life sciences and food science.
CD-ROM includes animations, living graphs, biochemistry in 3D structure tutorials.
Quantitative Understanding of Biosystems: An Introduction to Biophysics focuses on the behavior and properties of microscopic structures that underlie living systems. It clearly describes the biological physics of macromolecules, subcellular structures, and whole cells, including interactions with light.Providing broad coverage of physics, chemistr
This book is for readers who do not specialize in biochemistry but who require a strong grasp of biochemical principles. The goal of this book is to enrich the coverage of chemistry while better highlighting the biological context. Once concepts and problem-solving skills have been mastered, readers are prepared to tackle the complexities of science, modern life, and their chosen professions.
