C16 3’-sulfo Galactosylceramide is a member of the sulfatide class of glycolipids. It is one of the most abundant sulfatides found in porcine brain and plasma. Levels of short-chain sulfatides, including C16-C20 3’-sulfo galactosylceramides, decrease throughout development in mice. C16 3’-sulfo Galactosylceramide inhibits retinal ganglion cell neurite outgrowth in vitro. It is increased in dried urine spots and dried blood spots from patients with metachromatic leukodystrophy (MLD). C16 3’-sulfo Galactosylceramide has been used as an internal standard for the quantification of sulfatides in rat cerebellum and isolated white matter from patients with multiple sclerosis.
