Methyl 2,3,4-Tri-O-benzyl-D-galactopyranoside is a biochemical reagent used in the study of glycobiology. Glycobiology examines the structure, synthesis, biology, and evolution of sugars, including aspects such as carbohydrate chemistry, glycan synthesis and degradation enzymology, protein-glycan interactions, and the role of glycans in biological systems. This field is closely linked to fundamental research, biomedicine, and biotechnology.
