Linkages of cellulose
NettetCellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains. ... Cellulose is an unbranched polymer of glucose residues put together via beta-1,4 linkages, which allow the molecule to form long and straight chains. NettetWhen beta-glucose (the —OH is on the same side as the C6 carbon) forms the polymer cellulose, the linkage occurs through beta 1–4 glycosidic bonds. This arrangement …
