2,3-O-(1-Methylethylidene)-D-ribose is a biochemical reagent used in glycobiology research. Glycobiology focuses on the study of sugar structures, synthesis, biology, and evolution, involving carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and the role of glycans in biological systems. This field is closely linked with fundamental research, biomedicine, and biotechnology.
