Cellulose - Wikipedia
Cellulose is a straight chain polymer. Unlike starch, no coiling or branching occurs and the molecule adopts an extended and rather stiff rod-like conformation, aided by the equatorial conformation of the glucose residues.
Cellulose - Definition, Formula, Structure, Functions, and Diagram
2023年9月13日 · The polymerization of glucose units forms long chains, which combine to create the cellulose microfibrils, a critical structural component in plant cell walls. The hydroxyl groups (-OH) on the glucose molecules form hydrogen bonds with oxygen atoms.
Cellulose - Chemistry LibreTexts
Cellulose is a linear polysaccharide polymer with many glucose monosaccharide units. The acetal linkage is beta which makes it different from starch. This peculiar difference in acetal linkages results in a major difference in digestibility in humans.
Cellulose (C6H10O5)n - Structure, Molecular Mass, Properties, …
Cellulose is a long chain of sugar molecules linked together which gives wood its remarkable strength. It is the key component of cell walls for plants and the essential building block for many textiles and papers. The cellulose chain links are one sugar type: ß-D-glucose.
5.1: Starch and Cellulose - Chemistry LibreTexts
Cellulose yields D-glucose after complete acid hydrolysis, yet humans are unable to metabolize cellulose as a source of glucose. Our digestive juices lack enzymes that can hydrolyze the β-glycosidic linkages found in cellulose, so although we can eat potatoes, we cannot eat grass.

2003年12月11日 · Many features are common to both crystal forms. Each cellulose chain approximates to a flat ribbon, with alternate glucose units facing in opposite directions.
anhydroglucose unit (AGU) within the cellulose chain, a primary group at C6 and two secondary groups at C2 and C3 that are positioned in the plane of the ring (Fig. 2).
