Propargyl α-D-mannopyranoside (α-D-Mannopyranoside, 2-propyn-1-yl) is a biochemical reagent employed in glycobiology research. This field investigates the structure, synthesis, biology, and evolution of sugars, including carbohydrate chemistry, enzymes involved in glycan formation and degradation, protein-glycan interactions, and glycans' roles in biological systems. Glycobiology is closely linked with fundamental research, biomedicine, and biotechnology.
