Schematic of the changes in the collagen triple helices and the intermolecular structure in collagen fibrils when temperature increases. Two populations of fibrils are shown: (i) intact collagen fibrils, with unchanged axial packing under heat, and (ii) denaturing collagen fibrils, showing a decrease in the axial packing distance (blue arrows) and swelling in the lateral direction during thermal denaturation (red arrows). The high density of crosslinks (green links) between the collagen molecules of the intact fibrils, or the compression in the lateral direction (green arrows) caused by the swelling of adjacent fibrils, could contribute to the increase in structural constraint and heat stability.
