Metabolite Identification
Common NameSialyllacto-N-neotetraose c
DescriptionSialyllacto-N-neotetraose c is an oligosaccharide found in human breast milk. Two additional sialylated pentasaccharides include sialyllacto-N-tetraose-a and -b. Oligosaccharides containing N-acetyl (or N-glycolyl) neuraminic acid, i.e. sialylated oligosaccharides, are important components of glycoproteins and glycolipids. In nature, sialylated oligosaccharides often occur as homologous series, with incremental differences in composition, and as structural isomers with subtle differences in monosaccharide sequence and glycosyl linkage and, possibly, with presence or absence of molecular branching. A large number of such sialylated oligosaccharides occur in human milk, where they may have important biological functions. Major structural isomers of these acidic oligosaccharides in human milk are 3'- and 6'-sialyllactoses and the sialyllacto-N-tetraoses; appreciable amounts of 3'- and 6'-sialyllactosamines are found in human urine. (PMID:11471815 ). Oligosaccharides in human milk inhibit enteric pathogens in vitro and in vivo. Neutral milk oligosaccharides vary among individuals and over the course of lactation. (PMID:10683228 ).
