## Abstract Sialyloligosaccharides are synthesised by various glycosyltransferases and sugar nucleotides. All of these nucleotides are diphosphate compounds except for cytidine‐5′‐monophosphosialic acid (CMP‐Neu5Ac). To obtain an insight into why cytidine‐5′‐diphosphosialic acid (CDP‐Neu5Ac) has no
A position isomer of ganglioside GD3 has been synthesized in which N-acetylneuraminic acid (Neu5Ac) is linked alpha-glycosidically at C-9 of the Neu5Ac residue of the ganglioside GM3, structure.
