Sugars play important biological roles in lipid membranes, serving, for example, as protectants against freezing and dehydration in plants.  Understanding how sugars protect cell membranes could be quite helpful in better preserving cell membranes in human organs destined for transplant.  Despite these substantial motivations, the mechanism by which the sugars work is not yet understood.  In fact, a number of researchers have come to opposite conclusions on whether sugars are included or excluded.  A compromise is emerging that argues for both inclusion and exclusion.  Our results can be used to support a quantitative model detailing where and how much sugar resides in a variety of lipid-water-sugar structures.
