A fibrous protein is a specific type of protein that forms long, extended filaments. It's secondary structure consists mainly of long stretches of antiparallel Beta sheets linked together by many disulphide and hydrogen bonds.[1] Fibrous proteins form many structural functions which include muscle fibres, tendons, collagen and elastin. They are well adapted to this role as they are strong and relatively inextensible due to the polypeptide chains in the beta pleated sheets already being greatly stretched out.[2]      

Some examples of fibrous proteins include Keratin and Collagen
