Chemistry pervades our lives, giving shape and character to the world around us. It molds our climate, fuels our transport, and gives food its taste and smell. Chemistry powers life itself. Chemistry for the Biosciences leads students through the chemical concepts that are essential to understanding biological systems, using everyday examples and analogies to build their confidence in mastering an often daunting subject. Offering clear, straightforward explanations, the text focuses on comprehension rather than on rote learning. Employing relevant biological examples throughout, it illustrates just how integral chemistry is to the biosciences. Self-assessment questions encourage students to monitor their progress. An expanded Companion Website features resources for students and instructors. New to this edition: * More extensive use of biological examples, particularly in those topics related to physical chemistry * New Maths Tool panels that provide extra explanations of key mathematical concepts * Extensive illustrations, now enhanced by a new two-color text design * Significantly expanded coverage of reaction mechanisms * Extended treatment of acids, bases, and buffers in chapter 16 * A substantially reorganized chapter on molecular interactions * Revised coverage of chemical analysis now includes centrifugation and a more in-depth treatment of the conceptual basis of spectroscopy
