  • systematic
  • Maltose Sucrose Lactose Trivial names, however, are not useful for most other oligosaccharides and, as such, systematic rules for the nomenclature of carbohydrates have been developed. (wikipedia.org)
  • The following example will help illustrate this concept: Allyl α-L-fucopyranosyl-(1→3)-[α-D-galactopyranosyl-(1→4)]-α-D-glucopyranosyl-(1→3)-α-D-galactopyranoside These systematic names are quite useful in that they provide information about the structure of the oligosaccharide. (wikipedia.org)
  • residue
  • The reducing end of an oligosaccharide is the monosaccharide residue with hemiacetal functionality, thereby capable of reducing the Tollens' reagent, while the non-reducing end is the monosaccharide residue in acetal form, thus incapable of reducing the Tollens' reagent. (wikipedia.org)
  • The reducing and non-reducing ends of an oligosaccharide are conventionally drawn with the reducing-end monosaccharide residue furthest to the right and the non-reducing (or terminal) end furthest to the left. (wikipedia.org)
  • chemical
  • Some oligosaccharides, for example maltose, sucrose, and lactose, were trivially named before their chemical constitution was determined, and these names are still used today. (wikipedia.org)
  • group
  • Naming of oligosaccharides proceeds from left to right (from the non-reducing end to the reducing end) as glycosyl [glycosyl]n glycoses or glycosyl [glycosyl]n glycosides, depending on whether or not the reducing end is a free hemiacetal group. (wikipedia.org)
  • digestible
  • Oligosaccharides are not digestible by human gut enzymes. (livestrong.com)
  • oligosaccharides *are* digestible - by coliform bacteria. (bio.net)
  • 1) Digestible means degraded by enzymes of the host and absorbed, non digestible means that the material reaches the colon 2) coliform bacteria are of no importance to flatulence 3) coliform bacteria (E.coli is the only one in the intestine) do not degrade many oligosaccharides (they do degrade and ferment fructooligosaccharides (FOS, Nutraflora) though) 4) flatulence is mainly due to clostridia.

  • effectively
  • With these two oligosaccharides infused together, MS 2 of their doubly-sodiated molecular ions at m/z 1169.5 (Figure 2) produces fragments corresponding to both N 5 H 5 -I and N 5 H 5 -II, with each oligosaccharide effectively contaminating the spectrum of the other. (bio-medicine.org)
