CAS 37758-47-7: Ganglioside GM1

Ganglioside GM1 is protective of the central nervous system and is used to study neurologic disorders.

Applications Ganglioside GM1 Sodium Salt (bovine brain) is a specific receptor for cholera toxin. References Fishman, P.H., et al.: J. Membr. Biol., 69, 85-97 (1982); Vlasova, I., et al.: Zh. Evol. Biokhim. Fiziol., 45, 465-471 (2009);

GM1 (sodium salt) has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with sialic acid linked α2,3 to the inner galactose residue, ceramide linked β to position 1 on the reducing terminal glucose residue (Ledeen, 2009), and is abundant in all mammalian brains, where it covers 10%–20% of the total ganglioside mixture. GM1 is found in epithelial membranes and is a key element for the detection of bacterial toxicity and viral infection. It is the intestinal receptor for cholera toxin, the B-subunits of heat-labile toxin (LTB) from E.coli, for rotavirus, and simian virus 40. GM1 functions as a neurotrophic and neuroprotective compound and has been used therapeutically for diabetic and peripheral neuropathies. It also has the ability to bind amyloid-β proteins and is involved in Alzheimer’s pathogenesis (Chiricozzi, 2020).
