Recent advance in infant nutrition: Human milk oligosaccharides

Human Milk Oligosaccharides Important for Infant Defense

Oligosaccharides of Human Milk

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 + 3...

Associations between human milk oligosaccharides and infant body composition in the first 6 mo of life.

BACKGROUND Evidence linking breastfeeding to reduced risk of developing childhood obesity is inconclusive, yet previous studies have not considered variation in specific components of breast milk that may affect early development. OBJECTIVE We examined whether differences in the composition of human milk oligosaccharides (HMOs) correlate with infant growth and body composition at 1 and 6 mo o...

Variation in consumption of human milk oligosaccharides by infant gut-associated strains of Bifidobacterium breve.

Human milk contains a high concentration of complex oligosaccharides that influence the composition of the intestinal microbiota in breast-fed infants. Previous studies have indicated that select species such as Bifidobacterium longum subsp. infantis and Bifidobacterium bifidum can utilize human milk oligosaccharides (HMO) in vitro as the sole carbon source, while the relatively few B. longum s...
