Description
C18 globotriaosylceramide is an endogenous sphingolipid found in mammalian cell membranes that is synthesized from lactosylceramide . It inhibits aggregation of human neutrophils induced by phorbol 12-myristate 13-acetate (PMA; 10008014) when used at a concentration of 1 μM. C18 globotriaosylceramide acts as a receptor for Shiga toxin in B cell-derived Raji cells and THP-1 monocytes. It accumulates in the brain, heart, kidney, liver, lung, and spleen in a mouse model of Fabry disease, a lysosomal storage disorder characterized by a deficiency in the enzyme α-galactosidase A. C18 globotriaosylceramide also accumulates in endothelial cells, pericytes, vascular smooth muscle cells, renal epithelial cells, dorsal ganglia neuronal cells, and myocardial cells in patients with Fabry disease.

Definition
ChEBI: Alpha-D-Gal-(1->4)-beta-D-Gal-(1->4)-beta-D-Glc-(1<->1')-Cer(d18:1/18:0) is a glycotriaosylceramide having alpha-D-galactosyl-(1->4)-beta-D-galactosyl-(1->4)-beta-D-glucosyl as the glycotriaosyl component attached to the Cer(d18:1/18:0). It has a role as a mouse metabolite. It is functionally related to an octadecanoic acid.
