The molecule is a branched amino tetrasaccharide comprised of an alpha-D-mannosyl residue linked (1->6) to the middle mannose of alpha-D-Man-(1->3)-beta-D-Man-(1->4)-beta-D-GlcNAc. An intermediate glycan structure of glycosylated proteins. It is a glucosamine oligosaccharide and an amino tetrasaccharide.
