Cysteine is converted to cystine which is readily transported into mammalian cells. In the cells, cystine is converted back to cysteine, an essential amino acid needed to synthesize biomolecules such as proteins, or Coenzyme A3. What reagents would you choose to make the disulfide bond in the lab? Choose all that would produce the disulfide bond.
