Animal Hormones: A Comparative Survey, Part I—Kinetic and Metabolic Hormones provides a comprehensive coverage of the properties of kinetic and metabolic hormones of both vertebrates and invertebrates; the title particularly covers the sources, actions, and secretion of the said hormones. The text first details the general concerns with the hormones, such as the history, chemical activators, mechanical activation, types, and identification. The next chapter covers the sources of kinetic and metabolic hormones. Chapters 3 and 4 tackle kinetic hormones, while Chapter 5 discusses metabolic hormones. The book will be of great interest to students, researchers, and practitioners of zoology and biochemistry.
