(2R,3S,4R,5R)-2-{[(2R,3R,4S,5R,6R)-4,5-dihydroxy-6-(hydroxymethyl)-3-{[(2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}oxan-2-yl]oxy}-4,5,6-trihydroxy-3-{[(2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}hexanal
描述
Lactodifucotetraose (LDFT) 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. Lactodifucotetraose decreased substantially until day 5 in human milk and appeared to stabilize in the following days. (PMID: 15343178, 17375110, 2246719)
Lactodifucotetraose is a normal blood-group-active oligosaccharide excreted as a component of the urine in type O (H) secretors. (PMID 510288) [HMDB]
