Metabolite Identification
Common NameGanglioside GM2 (d18:0/18:0)
DescriptionGanglioside GM2 (d18:0/18:0) belongs to the class of organic compounds known as glycosphingolipids. These are sphingolipids containing a saccharide moiety glycosidically attached to the sphingoid base. Although saccharide moieties are mostly O-glycosidically linked to the ceramide moiety, other sphingolipids with glycosidic bonds of other types (e.g. S-,C-, or N-type) has been reported. Ganglioside GM2 (d18:0/18:0) is an extremely weak basic (essentially neutral) compound (based on its pKa).
