The 30th Anniversary edition of Harper's Illustrated Biochemistry continues its timely, integrated updating of biochemical knowledge, with repeated emphasis on its relationship to genetic diseases, clinical information, and the practice of medicine. This edition includes new full-color illustrations and tables, and numerous medically-relevant examples that present a clear and succinct review of those fundamentals of biochemistry that a student needs to understand for success in medical school. In addition to timely updating of content, the order of presentation of concepts has undergone major revision. The present 58 chapters are organized under an expanded list of eleven Sections. Chapters and topics in these sections emphasize integrated coverage of biochemical disease and clinical information. A major change has been that following the retirement of Dr. Murray, authorship and revision of his thirteen chapters have been assumed by Drs. Bender, Botham, Kennelly and Rodwell. For example, Section X contains a new chapter on white blood cells, and Section XI features nine entirely new, open-ended clinical case problems that emphasize clinical relevance and test both knowledge and understanding. To facilitate a student's grasp of each group of concepts, Question Sets now appear after each of the eleven new Sections. Many new questions have been added, and an Answer Bank follows the last chapter. New to this edition is the Answer Bank's inclusion of comprehensive explanations of many answers.
