Since its first edition in 1975, this extraordinary textbook has helped shape the way that biochemistry is taught, and has become one of the most trusted books in the field. It offers exceptionally clear writing, innovative graphics, coverage of the latest research techniques and advances, and a signature emphasis on physiological and medical relevance. The seventh edition has been updated throughout, including many new advances on genetic regulation, and revamped coverage of the integration of metabolism in the context of diet and obesity. Numerous new medical examples have been added throughout to make biochemistry real and relevant to students. The addition of new contributing author Gregory Gatto, an active pharmaceutical researcher at GlaxoSmithKline, ensures that the seventh edition presents the latest techniques that students need to understand in biochemistry research today. The end-of-chapter problems have also been revised and updated, providing students with great new exercises to test their understanding. The book is supported by a companion website (www.whfreeman.com/berg7e) which provides a variety of tools to aid understanding and learning including concept-based tutorials, animated techniques, self-assessment tools, and living figures that allow protein structures to be explored in 3-D.
