Metabolite Identification
Common NameGanglioside GM2 (d18:1/26:0)
DescriptionGanglioside GM2 (d18:1/26:0), also known as ganglioside GM2 or ii3neuacggose3cer, belongs to the class of organic compounds known as ceramides. These are lipid molecules containing a sphingosine in which the amine group is linked to a fatty acid. Ganglioside GM2 (d18:1/26:0) is an extremely weak basic (essentially neutral) compound (based on its pKa).
