| sphingolipid |
a lipid in which the backbone is sphingosine or a related base; the basic unit is a ceramide (q.v.) which is attached via its 1-hydroxyl group to a polar head group. The sphingolipids include sphingomyelins, cerebrosides, and gangliosides.

| sphingolipid activator p. |
any of a group of non-enzymatic lysosomal proteins that stimulate the actions of specific lysosomal hydrolases by binding and solubilizing their sphingolipid substrates. SAP-1 is a glycoprotein that binds sulfatide, ganglioside GM1, and ceramide trihexoside, activating cerebroside sulfatase, lysosomal β-galactosidase, and α-galactosidase activities, respectively. Deficiency of SAP-1, an autosomal recessive trait, results in a disorder considered to be a form of juvenile metachromatic leukodystrophy. SAP-2 is a glycoprotein necessary for the hydrolysis of ganglioside GM2 via activation of hexosaminidases A and B; deficiency of SAP-2 results in GM2 gangliosidosis, variant AB.
