  Cytokeratins / KRTs is one of a family of fibrous structural proteins known as scleroproteins.It is a α-helix. It is reached in amino acids like alanine,valine,leucine,isoleucine,methionine,phenylealanine. Two strands of α-keratin are oriented in parallel and are wrapped to each other to form a super twisted coiled coil. In α-helix there is presence of hydrogen bond and inter chain S-S cross link.
  It is the key structural material making up hair, nails, feathers, horns, (...)
