Starch: $\alpha$-$D$-glucose,$\alpha$-linkage; Cellulose: $\beta$-$D$-glucose,$\beta$-linkage; Glucose: Monosaccharide

(A) Starch is a polymer of $\alpha$-$D$-glucose units linked by $\alpha$-glycosidic linkages (specifically $C1-C4$ and $C1-C6$ linkages).Cellulose is a polymer of $\beta$-$D$-glucose units linked by $\beta$-glycosidic linkages ($C1-C4$ linkages).Glucose itself is a monosaccharide and does not contain any glycosidic linkages.
