Common Name | Disialyllactose |

Description | Disialyllactose is a naturally occurring oligosaccharide present in the cell surface and in breast milk. Disialyllactose has been identified as one of the binding sites of the C fragment of the clostridial tetanus toxin, binding with great specificity and high affinity. Clostridial neurotoxins, botulinum and tetanus, gain entry into motor neurons by binding to the sialic or N-acetylneuraminic acid (NeuAc) residues of gangliosides and specific protein receptors attached to the cell's surface. Neurotoxins interact with motor neurons, blocking acetylcholine release and causing muscle paralysis and death. The glycosidic linkage between Neu5Ac and other monosaccharides is susceptible to hydrolysis at low pH, and disialyl lactose is unstable under acidic conditions.
