  • Fibrous proteins 

    tough and rope-shaped. They're also insoluble and strong. They're structural proteins and are fairly unreactive
  • Collagen is found in animal connective tissues, such as bone, skin and muscle. It is a very strong molecule. Minerals can bind to the protein to increase its rigidity e.g in bone
  • Keratin is found in many of the external structures of animals, such as skin, hair, nails, feathers and horns. It can either be flexible (as it is in skin) or hard and tough (as it is in nails).
  • Elastin is found in elastic connective tissue, such as skin, large blood vessels and some ligaments. It is elastic, so it allows tissues to return to their original shape after they have been stretched.
