3'-Sialyllactose (sodium salt)

3'-Sialyllactose consists of the monosaccharide N-acetylneuraminic acid linked to the galactosyl subunit of lactose at the 3 position. It is an abundant oligosaccharide in the milk of many mammals, including cows and humans, particularly postpartum. 3'-Sialyllactose avidly binds several viral strains, including strains of influenza, HIV-1, reovirus, and polyomavirus. In some cases, binding of 3'-sialyllactose to viral proteins alters viral infectivity. 3'-Sialyllactose also alters Helicobacter activity and impacts bacterial colonization of gut.Formal Name: O-(N-acetyl-alpha-neuraminosyl)-(2->3)-O-beta-D-galactopyranosyl-(1->4)-D-glucose, monosodium salt.
