The Mollusca, Volume 2: Environmental Biochemistry and Physiology provides information pertinent to the advances in the traditional areas of biochemistry and in other developed areas that have become a part of molluskan biochemistry. This book discusses the developments in the various aspects of molecular biomechanics and environmental biochemistry. Organized into 10 chapters, this volume begins with an overview of the comparative studies of the structure–function relationships in molluskan oxygen carriers. This text then describes the specific types and classes of molluskan respiratory proteins. Other chapters consider the nature and distribution of respiratory proteins in mollusks. This book discusses as well the oxygen equilibrium properties of gastropod hemocyanins. The final chapter deals with host–symbiont interactions in mollusks. This book is a valuable resource for researchers of the Mollusca and other phyla, as well as to teachers and qualified graduate students. Biochemists and physiologists will also find this book useful.
