| Common Name | Ganglioside GM2 (d18:0/16:0) |
|---|
| Description | Ganglioside GM2 (d18:0/16:0) 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 (d18:0/16:0) is an extremely weak basic (essentially neutral) compound (based on its pKa). |
