Oligosaccharides

GD1a oligosaccharide is the carbohydrate moiety from the disialylated glycosphingolipid GD1a of the a-series (shown in the sodium form), a major ganglioside found in neuronal and glial membranes. GD1a oligosaccharide has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with sialic acids linked α2,3/α2,8 to the inner galactose residue, α2,3 to the outer galactose residue (Ledeen, 2009). GD1a ganglioside interacts with myelin-associated glycoprotein (MAG) and is essential for long-term axon-myelin stability. GD1a ganglioside plays a role in viral infection as it is a receptor for viral glycoproteins in rotavirus and paramyxovirus 1. The hexasaccharide GD1a moiety was also found on a glycoprotein that acts as a receptor for adenovirus type 37. Additionally, GD1a ganglioside interacts with botulinum neurotoxin (BoNT) and is crucial for its entry into cells (Kolter, 2012).

2-Acetamido-2-deoxy-4-O-(6-sulfo-b-D-galactopyranosyl)-b-D-glucopyranose sodium salt (6F3G) is a synthetic, fluorinated monosaccharide that has been used as a probe for the study of glycosylation and polysaccharide synthesis. 6F3G has been shown to be an effective inhibitor of the enzyme D-glycerate kinase, which catalyzes the conversion of D-glycerate to phosphoenolpyruvate. This inhibition leads to a decrease in the formation of ATP and NADH, which provides evidence that 6F3G binds to the active site of this enzyme.
