DOI: 10.1016/j.carbpol.2021.118193
Abstract: Most polysaccharides used in polysaccharide-based block copolymers are attached to the second block through the reducing end, due to the few and highly polysaccharide specific non-reducing end (NRE) functionalisation methods available. Chitin oligomers, prepared by… read more here.

DOI: 10.1021/acs.biomac.3c00104
Abstract: Site-specific modification is a great challenge for polysaccharide scientists. Chemo- and regioselective modification of polysaccharide chains can provide many useful natural-based materials and help us illuminate fundamental structure-property relationships of polysaccharide derivatives. The hemiacetal reducing… read more here.

DOI: 10.1021/acsmacrolett.9b00838
Abstract: Herein, we demonstrate an effective approach toward functionalization of cellulose nanocrystal (CNC) reducing ends by means of a Knoevenagel condensation reaction with a reactive β-diketone (acetylacetone). The end-wise modification was elucidated by advanced NMR analysis,… read more here.

DOI: 10.1021/acsomega.8b02559
Abstract: In this work, we take advantage of the parallel organization of cellulose chains in cellulose I yielding an inherent chemical asymmetry of cellulose nanocrystals, i.e., reducing vs nonreducing end, to selectively modify only one end… read more here.

DOI: 10.1093/glycob/cwy085
Abstract: Galactans are linear polysaccharides of β(1→4)-linked galactose residues. Although they can antagonize galectin function, the nature of their binding to galectins needs to be better defined to develop them as drugs. Here, we investigated interactions… read more here.
