Question: 61
1. Which of the following is NOT a type of glycolipid?
- A. Cerebroside
- B. Globoside
- C. Ganglioside
- D. Sphingomyelin
Correct Answer: D
Explanation:
Glycolipids contain sugar moieties connected to their backbone. Sphingomyelin is not a glycolipid, but rather a phospholipid. This class can either have phosphatidylcholine or phosphatidylethanolamine as a head group and therefore contains a phosphodiester, not glycosidic, bond.
