Definition of Keratins
Keratin Keratin Ker"a*tin, n. [Gr. ke`ras, -atos, horn.] (Physiol.
Chem.)
A nitrogenous substance, or mixture of substances, containing
sulphur in a loose state of combination, and forming the
chemical basis of epidermal tissues, such as horn, hair,
feathers, and the like. It is an insoluble substance, and,
unlike elastin, is not dissolved even by gastric or
pancreatic juice. By decomposition with sulphuric acid it
yields leucin and tyrosin, as does albumin. Called also
epidermose.
