Common NameGanglioside GM2 (d18:1/23:0)
DescriptionGanglioside GM2 (d18:1/23:0) belongs to the class of organic compounds known as gangliosides. These are lipid molecules composed of a glycosphingolipid (ceramide and saccharide) with one or more sialic acids linked on the sugar chain. They are usually oligoglycosylceramides derived from lactosylceramide and containing a sialic acid residue such as N-acetylneuraminic acid. Ganglioside GM2 (d18:1/23:0) is an extremely weak basic (essentially neutral) compound (based on its pKa).
