context_page_description: GM3 is a type of ganglioside. The letter G refers to ganglioside, and M is for monosialic acid as it has one sialic acid only. The numbering is based on its relative mobility in electrophoresis among other monosialic gangliosides. Its structure can be condensed to NANA-Gal-Glc-ceramide. GM3 is the most common membrane-bound glycosphingolipid in tissues, composed of three monosaccharide groups attached to a ceramide backbone. GM3 serves as a precursor for other, more complex gangliosides. Like other gangliosides, GM3 is synthesized in the Golgi apparatus. It is then transported to the plasma membrane, where it functions in cellular signaling. GM3 also functions as an inhibitor; it inhibits cell growth, the function of growth factor receptors, and generation of cytokines by T cells.
