The fundamental structure of a cerebroside is ceramide. Monoglycosyl and oligoglycosylceramides having a mono or polysaccharide bonded glycosidically to the terminal OH group of ceramide are defined as cerebrosides. Sphingosine is the main long-chain base present in ceramide. Galactosylceramide is the principal glycosphingolipid in brain tissue.
Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid joined by an amide bond. Ceramides are found in high concentrations within the cell membrane of eukaryotic cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. [1]
Its structure can be condensed to NANA-Gal-Glc-ceramide. GM3 is the most common membrane-bound glycosphingolipid in tissues, composed of three monosaccharide groups attached to a ceramide backbone. [2] GM3 serves as a precursor for other, more complex gangliosides. Like other gangliosides, GM3 is synthesized in the Golgi apparatus.
Ceramide glucosyltransferase (or glucosylceramide synthase) is a glucosyltransferase enzyme involved in the production of glucocerebrosides (also called glucosylceramides). ). It is responsible for the first step in synthesis of all glycosphingolipids—critical components of cell membranes—from sphingolipids, attaching a glucose molecule (glycosylation) to produce a glucocerebroside product
Soft drinks with added sugar might increase a person's risk of type 2 diabetes by affecting their gut microbiome, new research suggests.
Structure of ceramide, galactosylceramide and glucosylceramide. Galactose or glucose sugars can be attached to a hydroxyl group of ceramide lipids in a different form of O-glycosylation, as it does not occur on proteins. [6] This forms glycosphingolipids, which are important for the localisation of receptors in membranes. [8]
