Myelin sheath of neuron is composed of:
Correct answer: A. Sphingolipids
- A. Sphingolipids
- B. Ethanolamine
- C. Choline
- D. Waxes
Explanation
The myelin sheath is primarily composed of lipids, and sphingolipids are a major component of it. More specifically, a type of sphingolipid called "sphingomyelin" is a key constituent of the myelin sheath. Sphingomyelin is a combination of a fatty acid, sphingosine, and a phosphate group. It forms a part of the lipid-rich layer that makes up the myelin sheath.

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.
