Question

(a) Locate the glycosidic linkage in the following disaccharide. (b) Number the carbon atoms in both
rings. (c) Classify the glycosidic linkage as α or β, and use numbers to designate its location.

Accepted Answer

a. and b. The glycosidic linkage labeled in red contains a carbon bonded to two oxygens—one ring oxygen as well as the oxygen that joins the two rings together. Each ring is numbered beginning at the carbon bonded to two oxygen atoms.

c. The disaccharide has an α glycosidic linkage since the C—O bond is drawn down. The glycosidic linkage joins C1 of one ring to C4 of the other ring, so the disaccharide contains a 1→4-α-glycosidic linkage.
