Metabolite Identification
Common NameDisialyllacto-N-hexaose II
DescriptionDisialyllacto-N-hexaose II is a sialylated oligosaccharide of human milk. Neutral milk oligosaccharides vary among individuals and over the course of lactation. Sialylated oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. In human milk, both free and bound sialylated oligosaccharides have potential biological activity and are known to inhibit viral infection. (PMID: 10683228 , 1778981 ).
