Question

What is the composition of compound lipids?

• A. Fatty acid + glycerol + proteins
• B. Fatty acid + glycerol + carbohydrates
• C. Fatty acid + glycerol + phosphate
• D. All of these

Answer 1

The correct option is D All of these

Compound lipids are esters of fatty acids with alcohol (mostly glycerol) along with a few additional groups as well (phosphorus, sugars, proteins). Compound lipids can be further subdivided into glycolipids, phospholipids and sphingolipids on the basis of the additional group that has been attached.

Glycolipids are made up of fatty acids, glycerol and carbohydrates.

Phospholipids are made up of fatty acids, glycerol and phosphate groups.

Sphingolipids contain sphingosine as the additional groups.
