Question

Denaturation of proteins can be carried out by

• A. heat
• B. mineral acids
• C. bases
• D. all of the above

Answer 1

The correct option is D all of the above

Denaturation of proteins can be carried out by heat, mineral acids or bases.

Denaturation is a process in which proteins lose their quaternary, tertiary and secondary structure which is present in their native state by application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent, radiation or heat.

If proteins in a living cell are denatured, it results in the disruption of cell activity and possibly cell death. Denatured proteins can exhibit a wide range of characteristics from loss of solubility to communal aggregation.
