The white fibres are chemically composed of collagen.
Collagen is an extracellular protein that is composed of three polypeptide chains in coiled form.
This protein forms very strong fibres that are found in the cartilages, tendons and other connective tissues.
Collagen is also present in the bones of the animal body.
There are 18 varieties of collagen, each with specific polypeptide chain.
