This text for a one-semester introduction is intended for students in any field of science or engineering who do not intend to become biochemistry majors. A beginning biology course, general chemistry, and at least one semester of organic chemistry are assumed as preparation. This fourth edition features expanded special interest boxes on new topics such as prions and genetic keys to cancer, plus increased chapter exercises, expanded coverage of nutrition, and two new chapters on protein purification and characterization and nucleic acid biotechnology techniques. The color art program has been further expanded so that chemical equations and structures receive more visual emphasis. Campbell teaches chemistry at Mount Holyoke University. Farrell teaches biochemistry at Colorado State University. Annotation c. Book News, Inc., Portland, OR (booknews.com) Read Less
