“…It is mediated by the action of membranebound glycosyltransferases and sialyltransferases, which catalyze the transfer of sugar nucleotide donors to sphingolipid acceptors. 1,9 The first step in ganglioside biosynthesis occurs at the cytosol-ER interface. There, the enzyme UDPglucose (Glc) Cer glucosyltransferase adds Glc to Cer to form the simplest glycolipid, glucosylceramide (GlcCer).…”

“…To form LacCer, galactosyltransferase I transfers a galactose (Gal) moiety from UDP-Gal. 9 Complex gangliosides that are more glycosylated are built by the stepwise addition of sugar nucleotides to LacCer. In particular, specific sialyltransferases generate GM3, GD3, and GT3, which are further converted across the cis-medialtrans-Golgi to complex gangliosides of the a-, b-, or c-series, respectively, by sequential addition of Gal, N-acetylgalactosamine (GalNac), or sialic acid residues.…”

“…Біосинтез гангліозидів [5], який у спрощеному вигляді представлено на рис.1, сприяє різноманітності мож-ливих гліканових ланцюгів цих молекул. Синтез гангліозидів починається із загаль-ного попередника -лактозилцераміду.…”

“…Gangliosides are amphipathic molecules composed of a ceramide lipid anchor attached to an externally oriented oligosaccharide chain of variable length and complexity 5 . They are found on the surface of essentially all mammalian cells but are particularly abundant on neuronal cell surfaces.…”
