GlcNAc1-β-6GalNAc-α-PNP is a type of biochemical reagent used in glycobiology research. Glycobiology explores the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and the role of glycans in biological systems. This field is closely associated with fundamental research, biomedicine, and biotechnology.
