The molecule is a disaccharide derivative that is 4-O-(D-galactopyranosyl)-D-glucopyranose in which the hydroxy group at position 2 of the galactopyranose moiety has been converted into the corresponding hydrogen sulfate derivative. It is a disaccharide derivative, a partially-defined glycan and an oligosaccharide sulfate.
