The bond that links two monosaccharides in a disaccharide is a
- A. peptide bond
- B. ester bond
- C. phosphodiester bond
- D. glycosidic bond
Explanation
A glycosidic bond forms by condensation between the hydroxyl groups of two sugars. A peptide bond joins amino acids, an ester bond joins a fatty acid to glycerol, and a phosphodiester bond links nucleotides in nucleic acids, so each bond name points to its own family of molecules.
