Abstract
Applying statistical thermodynamic models for chain configurations in combination with linkage analysis, molar mass distribution and small angle X-ray scattering data allow the unambiguous structural elucidation of branched fructans. The radius of gyration of fructans can be accurately predicted by applying a random flight model with bond angle restrictions. The structural factor g has been calculated and correlated with experimental data only allowing a comb shaped structure for branched fructans. A formula for calculating the molar mass distribution of comb shaped branched fructans is proposed. Amalgamation of experimental and theoretical data prove a regular comb shape structure for the branched fructans of U. maritima, L. bulbiferum and A. tequilana.
