Metabolite Identification
Common NameNeolactotetraose
DescriptionNeolactotetraose (CAS: 13007-32-4), also known as lacto-N-neotetraose (LNnt), is a common oligosaccharide present in human breast milk. After lactose and lipids, human milk oligosaccharides (HMOs) are quantitatively the third largest and most diverse component of breast milk. These small mass HMOs are selectively metabolized by select bifidobacterial strains and represent a potential new class of bioactive molecules functioning as prebiotics to facilitate protective gut colonization in breast-fed newborns. The oligosaccharide composition of human milk varies among individuals. The geographical origin of the donors is one of the factors that account for this variability. This can be explained by genetically determined traits that are not uniformly distributed (PMID: 10420591 , 10697138 , 1370278 , 14533820 , 16239538 , 16441441 , 17101655 , 17372007 , 1910009 , 2452383 , 2474254 , 2988366 , 3926023 , 6083447 , 6798116 , 6874813 , 8193150 , 8416736 , 9353017 ).
