Identification Common Name Difucosyllactohexaose Class Small Molecule Description Difucosyllactohexaose is a fucosyloligosaccharide present in human milk and colostrum. Human colostrum is known to be important for the protection of infants against infection by pathogenic microorganisms. This protection is thought to be due, partially, to various neutral and acidic oligosaccharides that are present in colostrum and milk. Moderate-to-severe diarrhea of all causes occurs less often in infants whose milk contains high levels of total 2-linked fucosyloligosaccharides as a percent of milk oligosaccharide. Calicivirus diarrhea occurs less often in infants whose mother's milk contains high levels of fucosyloligosaccharides. (PMID: 16289347, 11273599, 3401331, 15343178, 17375110, 12568665).
