the quaternary level of protein structure.
QUESTION 18
When a protein is denatured, why does it lose its functionality?
Denaturation breaks the weak bonds (e.g. ionic & hydrogen bonds) that hold the protein in its 3-dimensional shape. Without the proper shape, the protein cannot function.
Denaturation breaks the covalent bonds that hold the protein in its 3-dimensional shape. Without the proper shape, the protein cannot function.
Denaturation destroys the primary structure of the protein, and the protein breaks down to monomers.
Different amino acids are substituted into the sequence, so the protein's properties change.
