kiulise kollageeni kõrgema astme polümeer, mis moodustab kudedes sadu mikromeetreid pikki ja peeni (ø 10-300 nm) struktuure
Collagen types I, II, III,V and XI self-assemble into D-periodic cross-striated fibrils. The fibril-forming collagen molecules consist of an uninterrupted triple helix of approx. 300 nm in length and 1.5 nm in diameter flanked by short extrahelical telopeptides. Combined fibrils form thicker bundles called collagen fibers.

Kui fibrillid ühinevad, siis tekivad jämedad kimbud, mida nimetatakse kollageeni kiududeks e fiibriteks.
