The glycosidic bond formation does not :
Involve the interaction of the H atom of one monosaccharide and the OH of another monosaccharide
involve addition of water molecule
Leads to the formation of a polysaccharide/oligosaccharide
Leads to the release of water molecule
bond is formed when an aldo- or keto- group in a sugar molecule combines with a hydroxyl group in another sugar unit.
Illustrate a glycosidic, peptide and a phosphodiester bond.
