Natural Proteinase Inhibitors focuses on natural inhibitors for proteolytic enzymes, which occur in plants and animals. It presents the theoretical and practical importance of the natural proteinase inhibitors of man and animal organisms. Organized into four chapters, this book starts with an overview of inhibitors for peptide and peptdohydrolases. This text then explores the important enzyme called kallikreins, which are found in the pancreas, the intestinal wall, the plasma, the submandibular gland, and the urine. Other chapters examine the various plant inhibitors, which are present in soybean, lima beans, potatoes, grains, and beetroots. This book discusses as well the inhibition of proteolytic enzymes by substances from body tissues. The final chapter deals with the prevention of uncontrolled liberation of kinins by proteinases, which is of great significance because the kinins are involved in the occurrence of pathological processes such as inflammation. Biologists and graduate students will find this book extremely useful.
