Lacto-N-fucoheptaose
IUPAC 名称
N-(2-{[2-({[3-acetamido-4-hydroxy-6-(hydroxymethyl)-5-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-2-yl]oxy}methyl)-3,5-dihydroxy-6-[(1,2,4,5-tetrahydroxy-6-oxohexan-3-yl)oxy]oxan-4-yl]oxy}-6-(hydroxymethyl)-5-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-5-[(3,4,5-trihydroxy-6-methyloxan-2-yl)oxy]oxan-3-yl)acetamide
描述
Lacto-N-fucoheptaose is a heptasaccharide found in human breast milk. It contains D(+)-galactose, D(+)-glucose, L(-)-fucose and N-acetyl-D(+)-glucosamine in a 3 : 1 : 1 : 2 ratio. The glucose residue is at the reducing end of the oligosaccharide. Milk oligosaccharides vary among individuals and over the course of lactation. Oligosaccharides are important components of glycoproteins and glycolipids and also occur as free oligosaccharides in several body fluids. In human milk, both free and bound oligosaccharides have potential biological activity and are known to inhibit viral infection. (PMID: 10744332, 7138030, 1132510) [HMDB]
