What type of glycosidic linkages are present in cellulose?
Options
- A-1,6
- B-1,4
- C-1,6
- D-1,4
Correct answer
B. -1,4
Step-by-step solution
Cellulose is a linear polysaccharide composed of D-glucose units connected by –1,4-glycosidic bonds, which contribute to its linear structure, robust hydrogen bonding, and resultant rigidity and insolubility. Unlike cellulose, starch (amylose) features –1,4-glycosidic bonds, while amylopectin and glycogen incorporate –1,6-glycosidic linkages at branch points. The correct identification is option B.
