The author's preface indicates that this book was designed to present concisely the fundamentals of biochemistry with emphasis on accepted facts and concepts as a supplement to standard textbooks. Much of the material in the book is drawn from the author's lectures in basic science given in conjunction with the graduate training of physicians. It is hoped that the book will serve as a review for the physicians preparing for state and specialty boards. Twenty-one well-organized chapters cover the essentials of intermediary metabolism of food materials, vitamins, enzymes, hormones, mineral and water metabolism and electrolyte equilibrium in body fluids, renal and hepatic function, etc. There are excellent tables listing data on the composition of body fluids and tissues, dietary requirements and normal values for various functional tests. Many diagrams represent normal metabolic pathways of intermediary metabolism and disturbances thereof in disease. The book packs a wealth of factual information.
