Detailed explanation-2: -The hard keratins comprising wool, hairs, quills, hooves, horns, nails and baleen contain partly alpha-helical polypeptides which show homology with epidermal polypeptides only in the helical regions.

Detailed explanation-3: -Keratins are a separate family of fibrous structural proteins that make up the main constituents of hair, nails, and hooves of other mammals. They are produced within cells identified as keratinocytes that are sequestered to the stratum corneum layer, that outermost, regenerative layer of the skin.
