Multiscale schematic representation of fibrillar collagen structure where triple-helical microfibrils formed of Gly-X-Y amino acid repeat units assemble in staggered orientation to form collagen fibrils, which in turn further assemble to form high molecular weight collagen fibers and bundles; denaturation of collagen disrupts this assembled structures to form gelatin, which can be partly reassembled into helical components to form lower molecular weight gels.
