Question

Denaturation is usually associated with transitions from helical structures to random coils. If an imaginary process were to transform the keratin in your hair from an

Answer 1

Yes.

Denaturation of a protein involves conformational changes. It involves the breaking of many of the weak linkages, or bonds such as hydrogen bonds, disulfide bonds, salt bridges etc. within a protein molecule. In an a -helix, the carbonyl of one amino acid is hydrogen bonded to the amino H (N-H) of an amino acid that is four down the chain and in a $\beta$ -pleated sheet, two or more segments of a polypeptide chain line up next to each other, forming a sheet like structure held together by hydrogen bonds. So when the structure of the fibrous protein is changed from $\alpha$ -helix to $\beta$ -pleated sheet structure, change in conformation, hydrogen bonding as well as in their secondary structure occurs, so the protein is said to be denatured.
