What is the covalent bond between two monosaccharide subunits called?
Correct answer: D. Glycosidic bond
- A. Phosphodiester bond
- B. Peptide bond
- C. Ionic bond
- D. Glycosidic bond
Explanation
The correct answer is the glycosidic bond, which is the covalent bond that forms between two monosaccharide subunits, allowing them to link together to form larger carbohydrate molecules like disaccharides and polysaccharides. This bond is crucial in the formation of complex carbohydrates. The other options are incorrect: phosphodiester bonds connect nucleotides in DNA and RNA, peptide bonds connect amino acids in proteins, and ionic bonds occur between charged ions, not between sugar molecules.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
