Common NameGanglioside GT2 (d18:1/22:1(13Z))
DescriptionGanglioside GT2 (d18:1/22:1(13Z)) 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 GT2 (d18:1/22:1(13Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa).
