Indeed, it is now much clearer that the water-soluble fiber (2) is richer in terms of monomer states and molecular motifs compared to fiber (1). Such diversity within fiber ( ) is consistent with recent experimental and computational observations that revealed that these water-soluble assemblies are way more dynamic and less ordered than expected. On the other hand, fiber (1) appears as a nearly perfect stack of monomers (similar to the cartoons of ideal fibers often used in the literature).
