Welcome to the Electronic Study Guide that accompanies the third edition of Biochemistry by Mathews, van Holde, and Ahern. At a time when major technological advances are occurring in both electronics and biochemistry, it is fitting that a CD-ROM accompanies this important biochemistry textbook.

The advantages of a CD-ROM are numerous. They include the ability to incorporate a considerably larger volume of material than the printed text and to exploit the computer as a learning aid. Towards this end, the CD-ROM contains Outlines, Concepts, Terminology, and Quizzing sections for each chapter in the textbook. Thus, the CD-ROM works with the textbook to make modern biochemistry as interesting and as accessible as possible.
