@aNsWeR →} Keratin is one of a family of fibrous structural proteins. It is the key structural material making up hair, horns, claws, hooves, and the outer layer of human skin. Keratin is also the protein that protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralizedepidermal appendages found in reptiles, birds, amphibians, and mammals.
The only other biological matter known to approximate the toughness of keratinized tissue is chitin.
