To which class do glycolipids belong?

• A. Proteins.
• B. Lipids.
• C. Carbohydrates.
• D. Nucleic acids.

Answer: (B)

Glycolipids are lipids with a carbohydrate group attached. The defining feature is a hydrophobic lipid tail that anchors in membranes, paired with a hydrophilic sugar head that sticks outward for cell recognition. Because the primary component is a lipid, glycolipids are classified as lipids, not as proteins, carbohydrates, or nucleic acids. The carbohydrate portion doesn’t redefine them as a carbohydrate; it’s just a functional head group. In contrast, proteins are built from amino acids, nucleic acids from nucleotides, and their overall structures and roles differ. So the best answer is that glycolipids belong to the lipid class.
