Comprehensive problem-solving support, engaging visuals, and a focus on the applications of chemistry combine to make this text an ideal match for allied health majors. Throughout the book, the author minimizes complicated mathematics. Early chapters focus on fundamental chemical principles while later chapters build on the foundation of these principles, developing the concepts and applications central to organic and biological chemistry. The Fourth Edition further develops the strengths of the previous editions with a refreshed, contemporary art program, additional challenging problems, and expanded Chemistry-at-a-Glance and Chemical Connections features. A complete technology package accompanies the text and features the new HM Testing program powered by Diploma, the new HM ClassPresent CD with videos and animations, and a new Eduspace online homework course. New! Multiple-Choice Practice Tests at the end of each chapter provide cumulative review opportunities for students. New! New or updated Chemistry-at-a-Glance sections visually summarize chapter concepts to help students comprehend difficult material while Chemical Connections boxes show chemistry as it relates to everyday life. New! Enhanced coverage of topics such as line-angle formulas; isomerism; glycolipids and glycoproteins; biochemically important small peptides; enzyme activity; the human genome project; DNA; RNA; and the electron transport chain provides students with the latest information on important organic and biological chemistry topics. New! A range of electronic resources on the HM ClassPrep CD and HM ClassPresent CD--including art, photos, scaleable lab demonstrations, and animations--allow instructors to easily demonstrate core chemistry concepts in the classroom. New! The Eduspace Online Learning Tool offers algorithmic end-of-chapter questions and Test Bank questions for unique test administration. New! The Online Study Center for students includes new tutorials with animations, videos, and exercises that test students' knowledge of chapter topics. In addition, a new math review covers the prerequisite math relevant to this course.
