Ganglioside GM3-d 7 is deuterium labeled Ganglioside GM3. Ganglioside GM3 is a precursor of a-, b-, and c-series gangliosides, interacts with transmembrane receptors such as the epidermal growth factor and insulin receptors, and regulates receptor functions by creating a specialized lipid environment. Ganglioside GM3 is synthesized by GM3 synthase and can be used for the research of hypercholesterolemia.
