Type III collagen is synthesized by cells as a pre-procollagen. The signal peptide is cleaved off producing a procollagen molecule. Three identical type III procollagen chains come together at the carboxy-terminal ends, and the structure is stabilized by the formation of disulphide bonds. Each individual chain folds into left-handed helix and the three chains are then wrapped together into a right-handed superhelix, the triple helix. Prior to assem… WebType III collagen, which adds structure and strength to connective tissues, is found in many places in the body, especially skin, lung, intestinal walls, and the walls of blood vessels. Collagen III is initially produced as procollagen, a protein consisting of three pro-alpha1(III) chains that form the triple-stranded, rope-like molecule. ...
