Opis

This unique volume provides an integrated overview of the subject of monovalent cations, specifically aimed at students and researchers. It is divided into two parts: the first deals with the processes by which monovalent cations are transported across biological membranes; the second deals with the processes that are affected by changes in intracellular cations. Each chapter describes in simple biochemical terms the interaction between one or more monovalent cations and a particular biological system of importance to current understanding of body function in health and disease. This useful publication is invaluable to students and researchers in biochemistry, physiology, neurology, pharmacology, anesthesiology, cardio-pulmonology, hematology, laboratory medicine, endocrinology, gastroenterology, internal medicine, psychiatry, urology, biomedical physics and medical nutrition.
