Pro-collagen then turns into tropocollagen which then is called a single collagen fiber.
Genipin molecules may react with amino groups within a tropocollagen molecule or between adjacent tropocollagen molecules to form intrahelical and interhelical cross-links in the genipin-fixed tissue [20].
The multicomposite tendon units are composed of several collagen fibres, known as tropocollagen (Figure 1) [3, 4, 6].
Collagen fibrils are formed from 300 nm long and 1.5 nm wide parallel tropocollagen arrays.
These globular regions are cleaved in varying degrees to give a polymerized structure (tropocollagen), which is the basic unit of collagen.

Later, there is excretion into the extracellular medium by exocytosis, where proteolytic enzymes cleave their C and N terminal propeptides, turning it into a tropocollagen. Then, tropocollagens bind together to form collagen fibrils, which give rise to collagen fibers [13].
