Collagen CAS 9007-34-5

Collagen, also known as collagen, is the main component of the extracellular matrix and mainly exists in the form of insoluble fibrin. It is widely present in the bones, tendons, muscle sheaths, ligaments, muscle membranes, cartilage, and skin of animals. It is an extremely important protein in connective tissue, accounting for 25% to 30% of the total protein in animals. It plays a role in supporting organs, protecting the body, and is also the most important functional protein that makes up the intercellular matrix. There are many types of collagen, generally type I collagen in skin and bones, type II collagen in cartilage, type III collagen in embryonic skin, and type IV collagen in the cell basement membrane. The structural characteristic of collagen is its triple helix structure, which makes the molecular structure very stable and has low immunogenicity and good biodegradability. Collagen, as a natural biological resource, has unique biocompatibility and biodegradability that cannot be compared to synthetic polymer materials today. In addition, it has other properties such as high tensile strength, low immunity, hemostatic performance, and promotion of cell growth. Therefore, it is widely used in fields such as clinical medicine, cosmetics, food, chemical raw materials and research.
