Microfibril
In type I collagen, and possibly all fibrillarcollagens if not all collagens, each of the triple helices forms a right-handed super-super-coil that is referred to as the collagen microfibril.
Thereafter, each of the microfibrilis interdigitatedor intercalated with its neighboring microfibrils. This strengthens the structure of the individual molecules.
