Chemistry for Biologists provides a focused yet chemically and mathematically rigorous introduction to those key aspects of chemistry that form the basis of biological processes. Written in a straightforward, accessible style, the book begins with an overview of basic chemical concepts. Building on these core principles, the reader is guided through subjects such as the structure and properties of organic molecules, equilibria, energetics, kinetics, biomolecules, reaction mechanisms, metabolism and structural methods. The relevance of each chemical concept to the study of biology is clearly explained at every stage, enabling students to develop a deep appreciation of the chemistry that underpins their chosen subject, and become confident in applying this knowledge to their own more
