PREFACE I n writing this seventh edition of Biochemistry, we have balanced the desire to present up-to-the minute advances with the need to make biochemistry as clear and engaging as possible for the student approaching the subject for the first time. Instructors and students have long relied on Biochemistry for: A straightforward and logical organization leads the reader through processes and helps navigate complex pathways and mechanisms.
Pathways and processes are presented in a physiological context so that the reader can see how biochemistry works in different parts of the body and under different environmental and hormonal conditions. These applications show students how biochemistry is relevant to them while reinforcing the concepts that they have just learned.
For a full list, see p. New to This Edition Researchers are making new discoveries in biochemistry every day. The seventh edition takes into account the discoveries that have changed how we think about the fundamental concepts in biochemistry and human health. New aspects of the book include: In this edition, we cover the integration of metabolism in the context of diet and obesity.
We have expanded explanations of mass spectrometry and x-ray crystallography, for instance, and made them even clearer for the first-time student. We explain new techniques such as next-generation sequencing and real-time PCR in the context of their importance to modern research in biochemistry. Campbell, Biochem. In addition to many traditional problems that test bio- chemical knowledge and the ability to use this knowl- edge, we have three categories of problems to address specific problem-solving skills.
These problems give students a sense of how scientific conclusions are reached. Brief solutions to these problems are presented at the end of the book; expanded solutions are available in the accompanying Student Companion. To help stu- dents read and understand these structures, we include the following tools: At this site, a variety of tools for visualizing and analyzing the structure are available.
Problems and resources from the printed textbook are incorporated throughout the eBook, to ensure that students can easily review specific concepts. The eBook enables students to: It features easy- to-use assessment tracking and grading tools that enable instructors to assign problems for practice, as homework, quizzes, or tests. A personalized calendar, an announcement center, and communication tools help instructors manage the course.
In addition to all the resources found on the Companion Web site, BiochemPortal includes several other features: Instructors teaching from the eBook can assign either the entire textbook or a custom version that includes only the chapters that correspond to their syllabi.
They can choose to add notes to any page of the eBook and share these notes with their students. These notes may include text, Web links, animations, or photographs.
Students can work through guided tutorials with embedded assessment questions, or explore the Metabolic Map on their own using the dragging and zooming functionality of the map. By working through the tutorial and answering assessment questions at the end of each exercise, students learn to use this important database and fully realize the relationship between structure and function of enzymes. Clarke help students build an intuitive understanding of some of the more difficult concepts covered in the textbook.
Students can test their understanding by taking an online multiple-choice quiz provided for each chapter, as well as a general chemistry review.

Additional experimental techniques are presented throughout the book, as appropriate. Exploring Proteins and Proteomes Chapter 3 Protein purification p. XI Acknowledgments Thanks go first and foremost to our students. Not a word was written or an illustration constructed without the knowledge that bright, engaged students would immediately detect vagueness and ambiguity.
We also thank our colleagues who supported, advised, instructed, and simply bore with us during this arduous task. We are also grateful to our colleagues through- out the world who patiently answered our questions and shared their insights into recent developments. Baserga and Erica A. We also especially thank those who served as reviewers for this new edition. Their thoughtful comments, suggestions, and encourage- ment have been of immense help to us in maintain- ing the excellence of the preceding editions.
These reviewers are: Freeman and Company on a number of projects, whereas one of us is new to the Freeman fam- ily. Our experiences have always been delightful and rewarding. Writing and producing the seventh edition of Biochemistry was no exception. The Freeman team has a knack for undertaking stressful, but exhilarating, projects and reducing the stress without reducing the exhilaration and a remarkable ability to coax without ever nagging.
We have many people to thank for this experience. First, we would like to acknowledge the encouragement, patience, excellent advice, and good humor of Kate Ahr Parker, Publisher.
Her enthusi- asm is source of energy for all of us. Lisa Samols is our wonderful developmental editor. Her insight, patience, and understanding contributed immensely to the suc- cess of this project. Beth Howe and Erica Champion assisted Lisa by developing several chapters, and we are grateful to them for their help. Georgia Lee Hadler, Senior Project Editor, managed the flow of the entire project, from copyediting through bound book, with her usual admirable efficiency.
Patricia Zimmerman and Nancy Brooks, our manuscript editors, enhanced the literary consistency and clarity of the text. Vicki Tomaselli, Design Manager, produced a design and layout that makes the book exciting and eye-catching while maintaining the link to past editions.
Janice Donnola, Illustration Coordinator, deftly directed the rendering of new illustra- tions.
Paul Rohloff, Production Coordinator, made sure that the significant difficulties of scheduling, composi- tion, and manufacturing were smoothly overcome. Amanda Dunning ably coordinated the print supplemants plan. Special thanks also to editorial assistant Anna Bristow. Debbie Clare, Associate Director of Marketing, enthusiastically introduced this newest edition of Biochemistry to the academic world. We are deeply appreciative of the sales staff for their enthusiastic support.
Without them, all of our excitement and enthusiasm would ultimately come to naught. Finally, we owe a deep debt of gratitude to Elizabeth Widdicombe, President ofW.
Freeman and Company. Her vision for science textbooks and her skill at gathering exceptional personnel make working with W. Freeman and Company a true pleasure. Thanks also to our many colleagues at our own insti- tutions as well as throughout the country who patiently answered our questions and encouraged us on our quest.
Without their support, comfort, and understand- ing, this endeavor could never have been undertaken, let alone successfully completed.
