| Common Name | Difucosyllacto-N-hexaose I |
|---|
| Description | Difucosyllacto-N-hexaose I is an oligosaccharide characterized in breast milk and found in feces of breast-fed infants. The oligosaccharides profile in the feces is similar to that of the ingested milk. Approximately 40% to 50% of the total ingested oligosaccharides can be found in feces of breast-fed infants. Oligosaccharides in human milk represent a group of bioactive molecules that have evolved to be an abundant and diverse component of human milk, even though they have no direct nutritive value to the infant. A recent hypothesis proposes that they could be substrates for the development of the intestinal microflora and the mucosal immune system. (PMID: 11787695 , 14530096 , 17002410 ). |
