Biochemistry 5th Edition has expanded integration of evolution, more chemical and structural insights
Opening a comprehensive biochemistry text for the first time can be a daunting experience for a neophyte. So much detailed material is presented that it is natural to wonder if you can possibly master it in one or two semesters of study. Of course, you can’t learn everything, but experience indicates that you can, indeed, learn the fundamental concepts in an introductory biochemistry course. We have written this Student Companion for Biochemistry to ease your entry into the exciting world of biochemistry.
Your goal is to “know” and “understand” biochemistry. Unfortunately, awareness of these grand goals offers no practical help in reaching them, because they are such high-level and complex intellectual processes. In addition, it is difficult for you to know to what extent you have attained them. We have found that, by subdividing these goals into simpler ones and expressing them in terms of demonstrable behaviors, you can begin to approach them and, in addition, can readily assay your progress toward reaching them. Thus, a part of each chapter consists of Learning Objectives that ask you to do things that will help you to begin to understand biochemistry. When you can master the objectives, you are well on your way to learning the material in the chapter. It is important to add a cautionary note here. Being able to respond to all the objectives adequately does not mean that you know biochemistry, for they are a limited sampling of all the possible objectives; more to the point, they do not explicitly require such higher-level activities as creation, analysis, integration, synthesis, problem-solving, evaluation, application, and appreciation. These more advanced skills will develop to varying levels as you continue your studies of biochemistry beyond the introductory stage.
Each chapter in the Companion consists of an introduction, Learning Objectives, a Self-Test, Answers to Self-Test, Problems, Answers to Problems, and Expanded Solutions to Text Problems. The introduction sets the scene, places the chapter material in the context of what you have already learned, and reminds you of material you may need to review in order to understand what follows. The Learning Objectives are presented in the order that the information they encompass appears in Biochemistry. Key Words—important concepts or vocabulary—are italicized in the objectives. Self-Test questions, requiring primarily information recall, are followed by the answers to the questions. A Problems section, in which more complex skills are tested, is followed by answers to the problems. Finally, Expanded Solutions to end-ofchapter problems in the text are presented.
The Companion may be used in many ways, and as you begin your studies you will develop the “system” that is best for you. Over 30 years of experience teaching introductory biochemistry to first-year medical students has suggested one pathway that you should consider. Start by reviewing the prerequisite chapters mentioned in the introduction and skim the Learning
