5410 Oligosaccharides of Human Milk
نویسنده
چکیده
Two new octasaccharides were isolated from human milk of a nonsecretor Lewis a+bindividual. Structural studies by sequential enzymic degradation and by quantitative methylation analysis revealed that their structures were as follows: Gal/31 + 3 (Fuccul + 4) GlcNAcPl + 3Gal/H -+ 4 (Fucal -+ 3) GlcNAcPl + 3Gal/31+ 4Glc, Gal/?1 + 4 (Fuccul -+ 3) GlcNAcj31 + 3Gal/31 -+ 4 (Fuccul -+ 3) GlcNAcj31 + 3GalPl -+ 4Glc. The core portions of these sugars, which are newly found linear hexasaccharides, are named para-la&o-N-hexaose and para-lacto-N-neohexaose, respectively.

Oligosaccharides from milk.
Feeding infants breast milk of healthy mothers is associated with a lower incidence of infectious and allergic diseases. Although this effect is of multifactorial origin, it is widely accepted that the entire intestinal flora of breast-fed infants provides antiinfective properties and is an important stimulating factor for the postnatal development of the immune system. The effect of human milk...
متن کاملStructures and application of oligosaccharides in human milk
Comparative study of the oligosaccharide profiles of individual human milk revealed the presence of three different patterns. Four oligosaccharides containing the Fucalpha1-2Gal group were missing in the milk of non-secretor, and three oligosaccharides containing the Fucalpha1-4GlcNAc group were missing in the milk of Lewis negative individuals. Disappearance of some major oligosaccharides in t...

Human milk, which nourishes the early infants, is a source of bioactive components for the infant growth, development and commensal formulation as well. Human milk oligosaccharide is a group of complex and diverse glycans that is apparently not absorbed in human gastrointestinal tract. Although most mammalian milk contains oligosaccharides, oligosaccharides in human milk exhibit unique features...
متن کاملVariation of human milk oligosaccharides in relation to milk groups and lactational periods.
Human milk oligosaccharides, representing the third largest fraction of human milk, have been assigned important protective functions for newborns acting as bifidogenic substrates or as inhibitory agents towards pathogens. Using high-pH anion-exchange chromatography and an enzyme test kit, twenty oligosaccharides and lactose were determined in milk samples of German women from days 3 to 90 post...

Neutral and acidic oligosaccharides were isolated from the milk or colostrum of four great ape species (chimpanzee (Pan troglodytes), bonobo (Pan paniscus), gorilla (Gorilla gorilla), and orangutan (Pongo pygmaeus)) and one lesser ape species (siamang (Symphalangus syndactylus)), and their chemical structures were characterized by (1)H-NMR spectroscopy. Oligosaccharides containing the type II u...
