C18 3'-sulfoGalactosylceramide is a member of the sulfatide class of glycolipids. Levels of short-chain sulfatides, including C18 3'-sulfogalactosylceramide, decrease with age in mice and humans. It is increased in brain from mice with an arylsulfatase A deficiency (ASA-KO), particularly in lipid raft fractions. Plasma levels of C18 3'-sulfogalactosylceramide positively correlate with disability progression in patients with relapsing-remitting multiple sclerosis using the Expanded Disability Status Scale. It is also increased in plasma from patients with metachromatic leukodystrophy (MLD).
C18:1 3'-sulfoGalactosylceramide is a member of the sulfatide class of glycolipids. It has been found in mouse brain. It has been used as a standard for the quantification of C18:1 3'-sulfogalactosylceramide in dried blood spots from patients with metachromatic leukodystrophy (MLD) by UPLC-MS.
