When the content of tropocollagen is up to 10%, it displays the best elasticity. 当原胶原蛋白含量达10%25时，纤维伸长率最大。
Tropocollagen subunits spontaneously self-assemble, with regularly staggered ends, into even larger arrays in the extracellular spaces of tissues. 另外脯氨酸所特有的肽平面夹角也是形成这种特殊螺旋结构的必须因素。
Bone formation Hydroxyapatite is deposited in nucleation sites between the ends of tropocollagen molecules as the first step in bone formation. 骨骼形成： 骨骼形成的第一步，羧基磷灰石被沉积在原胶原蛋白分子末羰之间的成核部位。
Collagen's insolubility was a barrier to study until it was found that tropocollagen from young animals can be extracted because it is not yet fully crosslinked. 胶原蛋白这种特殊的三股螺旋结构保证了它的机械强度。这种三股螺旋被称为原胶原。
