When an egg is cooked, the soluble globular protein albumin transforms into an insoluble fibrous protein. Bioactivity is lost throughout the denaturation process.

(ii) Albumin protein's secondary and tertiary structures are destroyed, but the primary structure (which contains the -amino acid sequence) is unaffected.

Although egg white is a fluid Ans, when it is cooked, the proteins get denatured and solidify as a result of coagulation.
