Keratin is the key structural material making up the outer layer of human skin. It is also the key structural component of hair and nails. Keratin is an example of fibrous proteins. The folding process for alpha-keratin can be summarized as the interaction between alpha helices. These interactions are mainly mediated by coiled coil protofilaments, filaments, hydrogen bonds, and hydrophobic interactions.
