Glycosphingolipids, Chemistry of

Abstract

Eukaryotic cell glycosphingolipids (GSLs) are central components of membrane lipid microdomains that function as trans plasmamembrane signaling foci. GSLs serve as important receptors and coreceptors, primarily to mediate host/microbial pathogen interactions, and undergo unique intracellular trafficking pathways. As such, their chemical modification can generate interventive therapeutic strategies and biologic probes. The process of achieving such goals via chemistry of the carbohydrate is in its infancy, but substitution within the lipid moiety has been used extensively. A consideration of the importance of the lipid moiety in GSL function has led to novel chemical approaches that attempt to retain this property.
