Lacto-N-fucopentaose I
IUPAC 名称
N-[(2S,3R,5S,6R)-2-{[(2R,3S,4S,5R,6S)-3,5-dihydroxy-2-(hydroxymethyl)-6-{[(2R,3R,4R,5R)-1,2,4,5-tetrahydroxy-6-oxohexan-3-yl]oxy}oxan-4-yl]oxy}-4-{[(2R,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}-5-hydroxy-6-(hydroxymethyl)oxan-3-yl]acetamide
描述
Lacto-n-fucopentaose I is an oligosaccharide found in human milk and other biofluids. Oligosaccharides of the blood group family decorate diverse glycoproteins and glycolipids on the surface of cells. Lacto-n-fucopentaose I and its sulfated and sialylated analogs, SuLNFPI and SLNFPI, are potent oligosaccharide ligands for the animal lectins, E- and L-selectin, and the natural killer cell receptor, NKR-P1. Burkinabe women show lower concentrations of lacto-n-fucopentaose I while Italian women show a higher concentrations of lacto-n-fucopentaose I. Lacto-n-fucopentaose I inhibits blastocyst attachment to uterine epithelial cells in vitro; component(s) carrying LNF-1 in the secretion might be regulatory molecules helping to secure the proper time for implantation.
