Extracellular matrix
α-keratin is a fibrous structural protein found in all vertebrates in hair, wool, stratum corneum of the skin, horns, nails, claws and hooves. It is a unique protein due to its insolubility in water. Its strength is due to a high sulphur content. Strong disulphide bonds make it insoluble in water and resistant to most chemical agents. The amino acid composition varies depending on the tissue in which it occurs.
