Features of This Companion Web Site
Each chapter in the textbook has a corresponding section on the Companion Web Site that contains Outlines, Concepts, Terminology, and Quizzing to help you succeed in your Biochemistry course.
  • Outlines sections parallel the organization of the individual chapters in the textbook, with hyperlinks to key concepts, figures, and pathways.
  • Concepts sections contain hyperlinked summaries of the important concepts from each chapter.
  • Terminology sections, which define the important terms from the text on a chapter-by-chapter basis, also include hyperlinks to appropriate figures.
  • Quizzing sections help you learn and retain the numerous terms, names, structures, enzymes, and pathways encountered in biochemistry. The Quizzing sections contain over 6000 queries to give you a thorough review and to make it possible to return many times without encountering the same question twice.

CD-ROM Access
When you're not on-line you can continue your study of biochemistry by using the CD-ROM found in the back of the book. The material available on this web site can also be found on the CD-ROM.

Connectivity to Expanded Information on the Internet
 The internet provides an incredible amount of information in Biochemistry. We have included hyperlinks between the concepts, enzymes, and molecules covered on the Companion Web Site to related information found on hundreds of external web sites. In doing so, the Companion Web Site provides an intellectual bridge between the textbook and an evolving body of knowledge that will undoubtedly grow with time, making this site a tool for learning biochemistry and an ongoing reference.
