Background:
C18 3'-sulfo Galactosylceramide-d3is intended for use as an internal standard for the quantification of C18 3'-sulfo galactosylceramide by GC- or LC-MS. C18 3'-sulfo Galactosylceramide is a minor endogenous sphingolipid produced from C18 ceramide and UDP-galactose in the endoplasmic reticulum followed by sulfation in the Golgi apparatus.1It is found in pro-oligodendroblasts and in neurons and accumulates in the lysosome of patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency.2,1,3C18 3'-sulfo Galactosylceramide also increases expression of indoleamine 2,3-dioxygenase 1 (DOX1) to catalyze the initial and rate-limiting step in kynurenine pathway tryptophan catabolism in antigen presenting cells to regulate several immune responses.1[Matreya, LLC.
