Question

Number of oxygen atoms in lipid molecules is always ......... as compared to number of carbon atoms

• A. Less
• B. More
• C. Equal
• D. Double

Answer 1

The correct option is A Less

Lipid is formed by ester linkage of the glycerol molecule with three fatty acid molecules. The reaction by which the lipids are formed is known as dehydration. It is an important constituent of the cell membrane. It has the hydrophobic tail which does not interact with water.
The ratio of C, H, and O in lipid molecule is generally - 1: 2: <1. So, for every single carbon atom there would be less than one oxygen atoms.

Hence, the correct answer is (A).
