Collagen CAS 9007-34-5

Collagen, also known as collagen protein, is a major component of the extracellular matrix, primarily existing in the form of insoluble fibrous protein. It is widely found in animal bones, tendons, muscle sheaths, ligaments, fascia, cartilage, and skin, and is an extremely important protein in connective tissue, accounting for 25%–30% of the total protein in an animal’s body. It plays a vital role in supporting organs and protecting the body, and is also the most important functional protein in the intercellular matrix. There are many types of collagen. Generally, type I collagen is found in skin and bones, type II collagen in cartilage, type III (Chemicalbook collagen) in embryonic skin, and type IV collagen in the cell basement membrane. Collagen is characterized by a triple helix structure. This unique triple helix structure makes the molecule very stable and gives it characteristics such as low immunogenicity and good biodegradability. Collagen, as a natural biological resource, possesses unique biocompatibility and biodegradability unmatched by modern synthetic polymers. It also boasts other properties such as high tensile strength, low immunogenicity, hemostatic properties, and cell growth promotion. Therefore, it is widely used in clinical medicine, cosmetics, food, chemical raw materials, and research.
