Methyl 6-deoxy-2-O-methyl-3,4-O-(1-methylethylidene)-α-D-galactopyranoside is a biochemical reagent employed in glycobiology research. Glycobiology focuses on the study of the structure, synthesis, biological roles, and evolution of sugars. This field encompasses carbohydrate chemistry, enzymology of glycan formation and degradation, protein-glycan interactions, and the role of glycans in biological systems, closely linking it to fundamental research, biomedicine, and biotechnology.
