6-O-[2-Acetamido-2-deoxy-4-O-(b-D-galactopyranosyl)-b-D-glucopyranosyl]-D-galactopyranose

The 6-O-[2-acetamido-2-deoxy-4-O-(b-D-galactopyranosyl)-b-D-glucopyranosyl]-D-galactopyranose is a disaccharide carbohydrate that can be found in the blood group H. This particular carbohydrate is an example of a sialic acid, which plays an important role in the immune system and other biological processes. Lectins are proteins that bind to carbohydrates and are often used as probes to study glycan structures. Lectin binding assays have been used to characterize this molecule as well as oligosaccharides, glycans, and biohazards.

Beta-D-Gal-(1->4)-beta-D-GlcNAc-(1->6)-D-Gal is an amino trisaccharide consisting of an N-acetyl-D-glucosamine flanked by two D-galactose residues in a linear sequence with (1->4) and (1->4) linkages. It is an amino trisaccharide and a glucosamine oligosaccharide.
