Metabolite Identification
Common NameDifucosyllacto-N-hexaose a
DescriptionDifucosyllacto-N-hexaose a is a difuco-derivative of lacto-N-hexaose isolated from human breast milk of a Lewis a positive donor. Human colostrum is known to be important for the protection of infants against infection by pathogenic microorganisms. Human milk contains numerous oligosaccharides. Their compositions are largely dependent on the blood type of the lactating mother. These oligosaccharides can be classified as either "acidic" or "neutral," depending on the presence or absence of sialic acid moieties. 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.
