Which of the following bonds is not created by a condensatio

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

Solution

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)
