Wills' Biochemical Basis of Medicine

Wills' Biochemical Basis of Medicine, Second Edition provides a basic understanding of the structure and metabolic processes in the context in which they occur in the cell or in the tissues. This book provides groundwork of academic biochemistry and demonstrations of the application of biochemistry to medicine. Organized into five parts encompassing 43 chapters, this edition begins with an overview of the biochemistry of the subcellular organelles. This text then examines the functions of the nucleus, mitochondria, and the endoplasmic reticulum. Other chapters consider the biochemistry of the hormones and the regulation of the metabolic fuels. This book discusses as well the biochemistry of environmental hazards and examines the treatment of viral carcinogenesis. The final chapter deals with the results of the application of recombinant DNA technology to the diagnosis of genetic disorder. This book is a valuable resource for biochemists, biologists, physicians, clinical researchers, and medical students.
