Question

_______ are esters of fatty acids with alcohol.

• A. fats
• B. complex lipids
• C. simple lipids
• D. compound lipids

Answer 1

The correct option is (C):

Explanation of the correct option:

1. The simple lipids are the components made out of fatty acids forming ester bond with alcohol.
   
2. These are also called homolipids and one common example is the triglyceride units.
   
3. They are made up of esters of fatty acid and glycerol associated with ester bonds. ​​

Explanation of the incorrect options:

Option (A):

1. Fats may contain single or multiple units of simple lipids together.
2. Therefore, only fatty acids and glycerol are not the components.

Option (B):

1. ​Lipids that possess an extra group associated with the fatty acids and glycerol are called complex lipids.
   
2. This extra group may include nitrogenous bases, carbohydrates, proteins and phosphates.
   
3. This includes the phospholipids and glycolipids.

Option (C):

1. Compound lipids include some derived lipids which possess one or more associated groups other than fatty acid and glycerol.
   
2. Steroids, terpenes, carotenoids are common examples of compound lipids.
   

Final Answer: Simple lipids are esters of fatty acids with alcohol.
