Also known as monosialotetrahexosylganglioside
GM1 (monosialotetrahexosylganglioside) the "prototype" ganglioside, is a member of the ganglio series of gangliosides which contain one sialic acid residue. GM1 has important physiological properties and impacts neuronal plasticity and repair mechanisms, and the release of neurotrophins in the brain. Besides its function in the physiology of the brain, GM1 acts as the site of binding for both cholera toxin and E. coli heat-labile enterotoxin (Traveller's diarrhea).

==GM1 and inherited disease== Galactosidases are enzymes that break down GM1, and the failure to remove GM1 results in GM1 gangliosidosis. GM1 gangliosidosis are inherited disorders that progressively destroy neurons in the brain and spinal cord as GM1 accumulates. Without treatment, this results in developmental decline and muscle weakness, eventually leading to severe retardation and death.
