Statistical model semiquantitatively approximates arabinoxylooligosaccharides’ structural diversity

A statistical model describing the random distribution of mono O-3 arabinofuranose substituted and double O-2 and O-3 arabinofuranose substituted xylopyranosyl residues in arabinoxylooligosaccharides is suggested. The suggested model can be applied for prediction and quantification of structural diversity of arabinoxylooligosaccharides, derived from different arabinoxylans. It can also be used the other way around for selection of arabinoxylan that is favorable for production of arabinoxylooligosaccharides with desired structural features, such as various prebiotic effects.

The model can also be applied for creating a mathematical standard for heteropolysaccharides, other than arabinoxylans, providing a robust theoretical benchmark for future experimental findings. Thus, the presented model should be of paramount interest for the first approximation of polysaccharides, for which the only available information is the ratio of monomeric residues.

In BioValue perspective this model opens for evaluations of commercial viability of a biorefinery process as it can predict estimates of biorefinery yield for specific oligosaccharides. We recommend using the model as guidance for selection of optimal biomass and to estimate yield/economy of a biorefinery process.
