The bond that links two monosaccharides in a disaccharide is a
Correct answer: D. glycosidic bond
- 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.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
