3. A biochemist purified a protein from the bloodstream and determined its molecular weight under several conditions. In 8 M urea, which denatures the polypeptide chain, the molecular weight of the protein was 150,000 Da. She found that under reducing conditions the molecular weight of the protein was 75,000 Da, while under oxidizing conditions the molecular weight of the protein was 150,000 Da. Explain these results.
