Markham St. Little Rock, AR 722057199 email: [email protected] Page xi Foreword These are very exciting times for biochemistry and especially for that part that pertains to human biology and human medicine. The much discussed Human Genome Project is likely to be completed very early in the next millennium, by the time most users of Textbook of Biochemistry With Clinical Correlations have graduated. The Human Genome Project should provide a blueprint of the 100,000 or so genes that the human genome is estimated to contain and lead to an explosion of amazing proportions in knowledge on complex physiological processes and multigenic disorders. This mapping will reveal undreamed of interrelationships and elucidate control mechanisms of the fundamental processes of development of the human organism and of their interactions with both milieus (the internal and external). Already, one eukaryotic genome (that of brewer's yeast, comprising 14 million base pairs in 16 chromosomes) was completed just before I set out to write this Foreword, while three microbial genomes (that of Mycoplasma genitalium—580,070 base pairs, Hemophilus influenzae—1.83 million base pairs, and Synechosystis—a photosynthetic organism—3.57 million base pairs) have been completed within 3 to 18 months of isolation of their DNA. Work on the genomes of Mycobacterium tuberculosis (4.5 million base pairs) and of Plasmodium falciparum—the malarial parasite (27 million base pairs in 14 chromosomes)—is now being undertaken and should lead to knowledge that can produce novel approaches to the treatment and control of these two scourges of humankind. The theoretical and technical principles involved in this type of work are clearly described in Chapters 14, 15, and 18 of Textbook of Biochemistry With Clinical Correlations, which will ensure that readers will understand and appreciate future developments in the field. Discoveries on the molecular basis of human disease are also being reported at an unprecedented and dizzying rate, opening wider and wider the window to many less frequent afflictions produced by mutated genes accumulating in the human gene pool. The era of molecular medicine has already arrived. Since the very first edition of Textbook of Biochemistry With Clinical Correlations, the correlations have been a feature that has made the book truly unique. In this new edition, the correlations are numerous, succinct, and integrated with, but also independent of, the text. They not only reflect current progress but indicate more than ever before how biochemistry, molecular biology, and human genetics have become the foundation stones of all areas of modern medicine. These previously separate disciplines have become so intimately and inextricably intertwined that little knowledge and understanding of one can occur without knowledge and understanding of others. One of the many strengths of this book is that clear examples of the convergence and integration of biological disciplines can be found in the clinical correlations. In this fourth edition of Textbook of Biochemistry With Clinical Correlations, the contributors have provided an uptodate and logical coverage of basic biochemistry, molecular biology, and normal and abnormal aspects of physiological chemistry. This material is appropriate and relevant for medical and other health science students, particularly as we approach the third millenium in the midst of amazing and pervasive progress in medical science and biotechnology. To enhance the text, a completely new series of vivid illustrations has been added, which will undoubtedly further the readers' understanding of the complexity of many of the concepts. Students of medical and health sciences should appreciate that the time and effort invested in learning the material presented here will be very well spent. This knowledge will provide the framework within which further developments will be understood and applied as the readers begin to care for the physical and mental well being of those entrusted to them. Furthermore, the knowledge derived from this book will also provide satisfying insight into the processes that underlie human life and the amazing power of the human mind to explore and understand it. As in previous editions, the fourth edition includes many multiple choice questions (and answers) at the end of each chapter that should facilitate this learning while ensuring success in professional and other examinations. I am happy and privileged to have watched the growth of human biochemistry (because of my teaching and research responsibilities) since my medical student days nearly halfacentury ago. It has been an amazing spectacle, full of thrills and exciting adventures into aspects of human cells that were previously shrouded in mystery and ignorance. As my knowledge has increased, so has my sense of awe and wonder at the unfolding beauty of this marvelous display of nature's secrets. As the late Alberto Sols frequently said: "The Biochemistry of today is the Medicine of tomorrow." Textbook of Biochemistry With Clinical Correlations illustrates the veracity of this insight.
