Explanation:

Biochemists working with proteins use a diverse set of treatments to analyze protein sequences. Denaturing agents unfold proteins. Some denaturing agents are reversible, and allow the proteins to be renatured after the procedure. A strong ethanol solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds

A strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.

  • Denaturing reversible agents can alter the secondary/tertiary structure of a protein without altering its primary structure.

  • Urea is a reversible denaturant that breaks hydrogen bonds in the secondary structure of proteins without modifying the primary structure.

  • 2-mercaptoethanol is a denaturing agent that cleaves disulfide bonds between cysteine residues.

In conclusion, a strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.
