An up-to date review of basic research on biomembranes. In this volume, foremost experts in the field consider the most important structural and functional aspects of biomembranes: - Membrane Lipids and Aging- Membrane-bound Enzymes- Ion Channels in Biological Membranes- Anion Exchangers of Mammalian Cell Membranes- Diversity of Transport Mechanisms in Bacteria.The volume is an excellent supplement to 'Biomembranes - Physical Aspects', also edited by Meir Shinitzky. Together these books provide a comprehensive ground for understanding complex physiological processes.Meir Shinitzky, Ph.D., is a Professor of Biophysics in the Department of Membrane Research and Biophysics, The Weizmann Institute of Science, Rehovot, Israel. Since 1971, his research has focused on various aspects of membrane structure and dynamics. Currently his main interest is in manipulation of membrane fluidity for clinical diagnoses and treatments. He has published extensively and is acknowledged worldwide as one of the leading experts in the increasingly significant field of biomembrane research.
