Sphingolipids are a class of lipids with a polar head group and two nonpolar tails. 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. They also serve as adhesion sites for extracellular proteins and play important roles in signal transmission and cell recognition. Sphingolipids are involved in diseases including diabetes, cancer, microbial infections, neurological syndromes, and cardiovascular disease. Types of Sphingolipids include Ceramides, Phytoceramide, Sphingomyelins, Glycosphingolipids, Gangliosides, Cerebrosides, and Sulfatides (sulfated cerebrosides).

There is a great deal of knowledge about sphingolipids from biochemical studies of their signaling properties, the cloning of enzymes of sphingolipid metabolism, the development of genetic models of their physiological roles, and from methods for their detection and quantitation. Sigma-Aldrich has a variety of products to aid sphingolipid research.
