The core of a sphingolipid is an amino alcohol called sphingosine. Complex sphingolipids located in the plasma membrane of animal cells (especially nerve cells) have a structural function and are believed to protect the cell surface from harmful environmental factors.
Glycolipids are glycoconjugates of lipids that are generally found on the extracellular face of eukaryotic cellular membranes, and function to maintain stability of the membrane and to facilitate cellâcell interactions.lycolipids can also act as receptors for viruses and other pathogens to enter cells. Gangliosides and cerebrosides that form glycosphingolipids (carbohydrate + sphingolipid) are two classes of glycolipids.
