Ethynyl estradiol 3-b-D-glucuronide is a type of biochemical reagent used for glycoscience research. Glycoscience focuses on the structure, synthesis, biology, and evolution of sugars, involving carbohydrate chemistry, glycans formation and degradation enzymology, protein-glycan recognition, and the role of glycans in biological systems. This field is closely related to basic research, biomedical sciences, and biotechnology.
