What are examples of fibrous structural proteins?
Examples of fibrous proteins include keratins, collagens and elastins. Fibrous proteins are only found in animals. Fibrous proteins form 'rod' or 'wire' -like shapes and are usually inert structural or storage proteins. They are generally water-insoluble. Fibrous proteins are usually used to construct connective tissues, tendons, bone matrix and muscle fiber.
Structural proteins are fibrous proteins. The most familiar of the fibrous proteins are probably the keratins, which form the protective covering of all land vertebrates: skin, fur, hair, wool, claws, nails, hooves, horns, scales, beaks and feathers. Equally widespread, if less visible, are the actin and myosin proteins of muscle tissue. Another group of fibrous structural proteins are the silks and insect fibers. In addition, there are the collagens of tendons and hides, which form…
