Collagen mutations result in osteogenesis imperfecta. Collagen is composed of three polypeptide chains, which wind around one another into a triple helix stabilised by covalent cross-linkages. Collagen is composed of regular arrangement of Gly-Pro-X, where X can be any amino acid. Glycine side chain is the only one that is small enough to fit into the centre of the triple helix. The angle of the proline residue enables the polypeptide chains to fold into the triple helical structure. People with osteogenesis imperfecta have bones that fracture easily, often from mild trauma.

Provides structural support and strength to various tissues and organs in the body. Collagen is a fibrous protein that forms a major component of the extracellular matrix, which is the non-cellular component that surrounds and supports cells.
In the case of the exoskeleton, which is the external skeleton found in many invertebrates such as insects and crustaceans, collagen plays a crucial role in providing rigidity and strength. The exoskeleton serves as a protective covering for the body, supporting and protecting the internal organs.
Collagen fibers in the exoskeleton provide structural integrity by forming a network of strong, flexible fibers. These fibers are arranged in a specific pattern, creating a lattice-like structure that gives the exoskeleton its rigidity and resistance to deformation.
The collagen fibers also contribute to the elasticity of the exoskeleton, allowing it to flex and bend without breaking. This is especially important for organisms with exoskeletons that need to move, as the collagen fibers provide the necessary flexibility for locomotion.
Furthermore, collagen in the exoskeleton helps to prevent water loss, as it forms a barrier that reduces evaporation. This is important for organisms living in arid environments or in water, as it helps maintain the internal moisture levels and prevents dehydration.
Overall, collagen is essential for maintaining the integrity of the exoskeleton by conferring rigidity, strength, flexibility, and moisture regulation. Without collagen, the exoskeleton would lack the necessary structural support to protect the organism and facilitate movement.
