Question

Differentiate between different structural proteins and identify examples of where they are used

Answer 1

Structural Protein:

the largest class of protein measured in terms of mass is the structural one. 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 connective ligaments within the body and give extra support to the skin where needed.,
