Question

what happens when proteins in egg white are denatured? a) new covalent bonds are formed between quaternary structures b) their amino acid sequence is lengthened c) they lose their 3d functional structure d) their amino acid sequence changes to form new functional proteins

Explanation:

Protein denaturation involves the disruption of the secondary, tertiary, and sometimes quaternary structures of a protein. The primary structure (amino - acid sequence) remains unchanged. When proteins are denatured, they lose their 3 - D functional structure due to the breaking of non - covalent bonds like hydrogen bonds, ionic bonds, and van der Waals forces. No new covalent bonds are formed between quaternary structures during simple denaturation, and the amino - acid sequence does not change.

Answer:

C. They lose their 3D functional structure
