Which of the following is NOT true about disulfide bonds?
Disulfide bonds form between two sulfur atoms.
The formation of a disulfide bond is an oxidation reaction.
The terms disulfide bonds and disulfide bridges are used interchangeably.
Disulfide bonds determine the three dimensional conformation of a protein.
Homework Answers
Disulfide bonds form between two sulfur atoms.- This statement is correct as it is formed between two sulfur atoms.
The formation of a disulfide bond is an oxidation reaction.- It is formed by oxidation reaction.
The terms disulfide bonds and disulfide bridges are used interchangeably.- These words are used interchangeably.
Disulfide bonds determine the three dimensional conformation of a protein.- This is false as as they stabilise the tertiary structure of a protein. They are not responsible for the three dimensional conformation of a protein.
So, the correct answer is D.

Tissue factor (TF) contains four cysteine residues that form two disulfide bonds in the native structure of TF. Suppose TF is reduced and unfolded in urea. If the reduced unfolded protein were oxidized prior to the removal of the urea, what fraction of the resulting mixture would you expect to possess native disulfide bonds?
