The collages are composed of three separate polypeptide chains braided into a rope-like triple helix Genetic defects in these collagens cause diseases such as Ehlers - Danlos syndrome, Scurvy Vitamin C deficiency, Osteogenesis imperfecta Defective regulation of collagen synthesis leads to hypertrophied scar, fibrosis and organ dysfunction. Morphologically, the smallest units of collagen are collagen fibrils.
