The characteristic of a protein that would remain intact even if the protein is denatured would be the number of amino acids.
Denaturation of proteins refers to the breakage of bonds responsible for the shapes of the secondary structure of the biomolecule.
Proteins are made from amino acids that are linked together by peptide bonds. The resulting polypeptide is then folded in a specific way to confer some functional attributes on it
When a protein is denatured, the loss of secondary structure leads to loss of functions. However, the primary structure which is essentially the component amino acids remains intact.
Denaturation also affects the solubility of proteins in water.
