Select the most appropriate example of the denaturation of protein.
a. egg albumin, which is a translucent fluid, changes to opaque white solid after boiling.
b. rice granules, which are smaller in size and translucent, appear larger and opaque white after cooking.
c. oil, if kept for a longer time at room temperature, turns rancid and appears discolored.

The correct answer would be A. Egg albumin, which is a translucent fluid, changes to opaque white solid after boiling.

Denaturation of protein refers to the disruption of the structure of the protein. It mainly involves the breakdown of the secondary and tertiary structure of the protein. The peptide bonds are usually not broken down and thus primary structure of the protein remains the same.

When eggs are heated or boiled, the egg proteins (such as albumin) get denatured and coagulate with each other forming an opaque, firm and rubbery mass.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
