WebThe collagen triple helix is made of three collagen peptides, each of which forms its own left-handed polyproline helix. When the three chains combine, the triple helix adopts a right-handed orientation. The collagen peptide is composed of repeats of Gly-X-Y, with the second residue (X) usually being Pro and the third (Y) being hydroxyproline. WebCollagen is distinct from other proteins in that the molecule comprises three polypeptide chains which form a unique triple-helical structure (See figure 1). It is tough and inextensible, with great tensile strength, and is the main component of cartilage, ligaments and tendons, and the main protein component of bone and teeth.

WebThe simplest is merely a long triple helix with blunt ends. These ‘type I’ collagen molecules associate side-by-side, like fibers in a rope, to form tough fibrils. These fibrils crisscross the space between nearly every one of our cells. WebJul 20, 2024 · Shoulders, M. D. & Raines, R. T. Collagen structure and stability. Annu. Rev. Biochem. 78, 929–958 (2009).
