Metabolite Identification
Common NameGalabiosylceramide (d18:1/26:1(17Z))
DescriptionGalabiosylceramide is a non-acidic diglycosphingolipids, i.e. a sphingolipid with two or more carbohydrate moieties attached to a ceramide unit. It is a vital component of cellular membranes of most eukaryotic organisms and some bacteria. Its abundance relative to other lipids is usually low other than in epithelial and neuronal cells. Galabiosylceramide has also been found in small amounts in kidney and pancreas, for example. Galabiosylceramide is one of the lipids that accumulates in excessive amounts in Fabry's disease. It is the precursor of the gala series of oligoglycosylceramides. An animal tissues, biosynthesis involves addition of a second monosaccharides unit from the appropriate sugar nucleotide to a monoglycosylceramide, catalysed by a glycosyl transferase, in the lumen of the Golgi apparatus. Glycolipids are important components of the body's immune defense system, either in haptenic reactivity or in antibody-producing potency, i.e. as cellular immunogens or antigens. Certain glycolipids are involved in the antigenicity of blood group determinants, while others bind to specific toxins or bacteria. Some also function as receptors for cellular recognition, and they can be specific for particular tissues or tumours.
