GalNAc1-b-3Gal-α-Ome (Methyl 3-O-[2-(acetylamino)-2-deoxy-β-D-galactopyranosyl]-α-D-galactopyranoside) is a biochemical reagent utilized in the study of glycobiology. This field explores the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan interactions, and the role of glycans in biological systems. Glycobiology is closely linked to fundamental research, biomedical sciences, and biotechnology.
