Nitrogenous bases such as choline and serine are a significant part of which of the following?
Correct answer: B. Phospholipids
- A. Sphingolipids
- B. Phospholipids
- C. Phosphodiester
- D. None of these
Explanation
Phospholipids are major components of cell membranes and include nitrogenous bases like choline and serine in their head groups. Specifically, phosphatidylcholine contains choline, and phosphatidylserine contains serine. These molecules play a critical role in forming the bilayer structure of cell membranes. Other options are incorrect: sphingolipids may sometimes contain choline in specific cases but are primarily based on sphingosine, phosphodiester bonds are related to nucleic acids, and none of these is not applicable as phospholipids do contain these nitrogenous bases.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
