Question

Which of the following macromolecules does not undergo dehydration synthesis during polymer formation?
Options
A Proteins
B Lipids (simple types like steroids)
Correct Answer
C Nucleic acids
D Polysaccharides
Correct Answer

Option B is the correct answer.

Detailed Explanation

Dehydration synthesis (condensation) is the process of linking monomers by removing a water molecule. Proteins, nucleic acids, and polysaccharides are all formed this way. Simple lipids like triglycerides are also formed by dehydration (ester linkage), but other lipids like steroids are not polymers and are not assembled from monomers via dehydration synthesis.

Hint

Steroids have a four-ring structure and are not built from repeating subunits.
