Phosphatidylcholine is one of the common:
Correct answer: A. Phospholipid
- A. Phospholipid
- B. Sphingolipid
- C. Glycolipid
- D. Terpenoid
Explanation
Phosphatidylcholine is a type of phospholipid, which is a major component of cell membranes. It consists of a glycerol backbone, two fatty acid tails, and a phosphate group linked to choline. This structure allows phospholipids to form bilayers, which are essential for cell membrane integrity and function. Sphingolipids, while also membrane components, have a sphingosine backbone and are not classified as phospholipids. Glycolipids contain carbohydrates and play different roles in cell recognition. Terpenoids are not related to phospholipids but are instead derived from terpenes, which are often involved in plant processes.

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.
