Glycerol is a component of:
Correct answer: D. Both B and C
- A. Fatty acids
- B. Acylglycerols
- C. Phospholipids
- D. Both B and C
Explanation
Glycerol is a crucial component in the structure of both acylglycerols and phospholipids. In acylglycerols, glycerol acts as the backbone to which one, two, or three fatty acid chains are esterified, forming mono-, di-, and triglycerides. In phospholipids, glycerol forms the backbone for two fatty acids and a phosphate group, which is often linked to another polar group. This combination of glycerol, fatty acids, and phosphate is essential for forming the lipid bilayer of cell membranes. Fatty acids themselves do not contain glycerol, which is why option A is incorrect.

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.
