Which of the following bonds is not created by a condensation/dehydration reaction?
a) peptide bond ( between amino acids)
b) phosphodiesterase bond ( between nucleotides)
c) glycosidic bond (between sugars)
d) ester linkage (connects glycerol to fatty acid)
e) they are all created by dehydration reactions
Homework Answers
Answer : The correct answer is E (They are all created by dehydration reactions). Formation of all these bonds /linkages involves dehydration. Water molecules are released during these processes (loss of a water molecule)

Which of the statements about peptide bonds are true? D A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bond formation is a hydrolysis reaction. O Peptides are polymers of amino acids. Peptide bonds form from nucleophilic attack by an a-carboxyl carbon atom on an electron pair of an a-amino nitrogen atom of another amino acid.
