Overview: Although not the only volume in this series in which lipids are discussed, the present volume is devoted entirely to methods for the study of membrane lipids. Even now, when membrane proteins are properly receiving so much attention, this emphasis on membrane lipids is appropriate. Essentially all of the phospholipids and sterols of cells are in membranes. Moreover, although membrane proteins are certainly of utmost importance, the more we learn about the functional properties of membrane proteins, the more we appreciate the unique features of phospholipids, without which biological
