Which of These Molecules is Not Formed by Dehydration Reactions

Question

Which of these molecules is not formed by dehydration reactions?
A) fatty acids
B) disaccharides
C) DNA
D) protein
E) amylose

Accepted Answer

Fatty acids are not formed by dehydration reactions; they are basic building blocks of lipids and are synthesized through various pathways involving the addition of two-carbon units, not through the removal of water molecules, which is characteristic of dehydration synthesis. Dehydration reactions are involved in forming disaccharides, DNA, proteins, and amylose by linking monomers and releasing water.
