"Handbook of Hormones: Comparative Endocrinology for Basic and Clinical Research is a convenient and comprehensive catalog of hormones for the benefit of all professionals in biomedical sciences as well as undergraduate and graduate students in biology, medicine, and related fields. This handbook is a unique resource that concisely provides basic but important information on structure and function of hormones across vertebrate and invertebrate phyla from the comparative viewpoint. It offers rapid and easy access to important and indispensable knowledge about the hormones and their receptors, including chemical and molecular structures, intracellular signaling pathways, and biological actions. Readers will find simple and visual ways to extract key, up-to-date information on hormone families. Online ancillary resources, together with the main text, integrate additional information, further providing molecular and functional considerations from an evolutionary perspective."
