Question

Which of the following molecules contains a glycosidic linkage type of covalent bond?

A) 13
B) 12
C) 4
D) 15
E) 6

Answer 1

The molecule that contains a glycosidic linkage type of covalent bond is 4. The option (C) is correct.

Step-by-step explanation:

The molecule that contains a glycosidic linkage type of covalent bond is 4.

A glycosidic bond is a covalent bond that forms between two monosaccharide molecules to create a disaccharide. This bond is formed through a dehydration synthesis reaction, where a hydroxyl group from one monosaccharide reacts with a hydroxyl group from another monosaccharide, resulting in the formation of a covalent glycosidic linkage.

For example, in maltose, the glycosidic bond forms between the alpha position of glucose and the beta position of another glucose molecule, creating an alpha-1,4-glycosidic bond. Therefore, option (C) is correct.
