Inulin is a linear 2–1 fructose polymer with degree of polymerization (DP) ranging from 2 to 60 (average DP of 12). Glucose or fructose can be found in the terminal position. FOS are also 2–1 fructose polymers, but the average DP is less than 10. In some cases, FOS ...
Analytical solution for the bivariate distribution W(r,k) of the degree of polymerization r and the number of branch points k is obtained for the random branching of polymer chains that follow the Schulz–Zimm distribution, or in mathematical term, the gamma distribution. It is found that when...

The index p in general formula (I) indicates the degree of polymerization (DP), i.e. the distribution of mono- and polyglycosides, and is a number of 1 to 10. Whereas p in a given compound must always be an integer and, above all, may assume a value of 1 to 6, the value p ...
Behavior in Fire: Vapors are heavier than air and may travel considerable distance to a source of ignition and flash back. Fires are difficult to control due to ease of reignition. (USCG, 1999)|Highly flammable. Vapour/air mixtures are explosive.|Flammable - 3rd degree GHS Classification: ...

It possesses [Special Properties], which make it suitable for various applications in [Application Fields]. Please note that the specific chemical formula and structure of this compound may vary depending on the degree of polymerization and the number of repeating units. 2D3D 9078-71-1 Structure...
Fucosylated oligosaccharide formation can be initiated by acceptor substrates starting from any degree of polymerization (DP), from DP=1 onwards. Alternatively, fucosylated oligosaccharides may be produced by chemical synthesis from lactose and free fucose. Fucosylated oligosaccharides are also available for...
