Question

which of the following below is not a dehydration reaction? forming a glycosidic bond between two monosaccharides. forming a peptide bond between two amino acids. linking two nucleotides together. breaking the bond between a fatty acid and a glycerol molecule.

Explanation:

Dehydration reactions involve the loss of a water molecule to form a covalent bond. Forming a peptide bond between two amino - acids, forming a glycosidic bond between two monosaccharides, and linking two nucleotides together are all dehydration reactions. Breaking the bond between a fatty acid and a glycerol molecule is a hydrolysis reaction (the reverse of a dehydration reaction), which involves the addition of a water molecule.

Answer:

Breaking the bond between a fatty acid and a glycerol molecule
