Question

Which of the following statements about the conformation (secondary and tertiary

structure) of proteins is FALSE?

a. The four atoms of an amide linkage (–CO–NH–) lie in a plane as a result of

resonance between the nitrogen and the carbonyl group.

b. Electrostatic attraction occurs between basic and acidic side chains.

c. The favored conformation of a protein is always that which has the greatest

number of hydrogen bonds.

d. The presence of the amino acid proline has the effect of turning a corner in a

protein.

Answer 1

The favored conformation of a protein is always that which has the greatest number of hydrogen bonds is the false statement.

answer is c.

Answer 2

Answer:

Here statement in option D is False.

Here statement in option D is False.Confirmation of protein is determined by the sequence of amino acids but not on hydrogen bonds.

Here statement in option D is False.Confirmation of protein is determined by the sequence of amino acids but not on hydrogen bonds.All other statements are correct.

Here statement in option D is False.Confirmation of protein is determined by the sequence of amino acids but not on hydrogen bonds.All other statements are correct.Proline causes a turning effect due to steric hindrance.

Here statement in option D is False.Confirmation of protein is determined by the sequence of amino acids but not on hydrogen bonds.All other statements are correct.Proline causes a turning effect due to steric hindrance.CONH lies in one plane for resonance

Here statement in option D is False.Confirmation of protein is determined by the sequence of amino acids but not on hydrogen bonds.All other statements are correct.Proline causes a turning effect due to steric hindrance.CONH lies in one plane for resonanceElectrostatic attraction occurs between acidic and basic side chains forms 1° and 2° structures.
