The molecule is a neoglycolipid consisting of a linear pentasaccharide made up from one lactamized sialyl residue, two galactose residues, one N-acetyl-6-sulfonatoglucosamine residue (with associated sodium cation) and one glucose residue, which at the reducing end is attached glycosidically to a 2-(tetradecyl)hexadecyl group. It is a neoglycolipid, an oligosaccharide sulfate and a glycoside. It contains a delta-lactam ring.
