Glycosidic bond is formed by the:

Explanation

Removal of water: The formation of a glycosidic bond involves the removal of a water molecule (H2O) from two hydroxyl groups of monosaccharide units. One hydroxyl group donates an -H (hydrogen atom), and the other donates an -OH (hydroxyl group). The loss of these two components (H and OH) results in the formation of a covalent bond (glycosidic bond) between the two monosaccharide units. Removal of oxygen: This option suggests that the glycosidic bond is formed by removing oxygen. However, this is not accurate. The glycosidic bond formation is related to the loss of water, not oxygen.Addition of oxygen: This option suggests that the glycosidic bond is formed by adding oxygen. However, this is not accurate. The glycosidic bond formation involves the removal of water, not the addition of oxygen. Addition of water: This option suggests that the glycosidic bond is formed by adding water. However, this is not accurate either. The glycosidic bond is formed by the removal of water, not the addition of water.In summary, option a) Removal of water is the correct option. The formation of a glycosidic bond involves the removal of a water molecule from two hydroxyl groups of monosaccharide units, leading to the covalent linkage between the two monosaccharides.
