human milk oligosaccharides are substrates and sole carbon source for Bifidobacterium bifidum colonizing the human intestinal tract. More than 130 types of human milk oligosaccharides have been isolated with the most abundant being lacto-N-tetraose, lacto-N-fucopentaose I, lacto-N-difucohexaose, and 2'-fucosyllactose |
| 3.2.1.140 | more |
the native substrate are human milk oligosaccharides. Among the different structures, four molecular species, namely 2'-fucosyllactose, lacto-N-tetraose, lacto-N-fucopentaose I, and lacto-N-difucohexaose I, are most abundantly present and comprise more than 50% of the total oligosaccharides, unless the milk is derived from non-secretor or Lewis-negative subjects |
