Living Chemistry is a 23-chapter textbook that provides a thorough, systematic coverage of the chemical information related to health. The opening chapters cover the basic concepts required for understanding the "language" and principles of chemistry. These chapters also introduce the International System of units followed by the studies of carbon compounds based on functional groups. The discussions then shift to the study of biologically important molecules, such as the chemistry of carbohydrates, lipids, and proteins, as well as the individual reaction steps for important complex metabolic pathways. The remaining chapters explore the chemistry of vitamins, hormones, body fluids, drugs and poisons. Optional topics, including a mathematics review, scientific notation, the unit-factor and proportion methods, metric conversion with practice problems, atomic orbitals, hybridization, metabolic pathways, and the cell, are provided in the supplementary texts. This book is of great value to undergraduate chemistry students.
