A glycosaminoglycan, a polysaccharide consisting of a repeating disaccharide unit formed by the connection of d-glucuronic acid and N-acetylgalactosamine by a β-1, 4-glucoside bond, sulfated on the C-4 or C-6 hydroxyl of n-acetylgalactosamine. It's rich in animal cartilage. Chondroitin sulfate can protect collagen fibers, promote the growth of fibers in the matrix, enhance permeability, improve blood circulation, accelerate metabolism, promote the absorption of osmotic substances, and eliminate inflammation. Its polyanion has strong water retention and can improve the water metabolism of tissues. It has a strong affinity for mucosa and can form a breathable water retaining membrane on the mucosal surface to improve the symptoms of mucosal dryness.

　　Heparins Manufacturer: Function of chondroitin sulfate:

　　1, chondroitin sulfate can effectively protect corneal collagen fiber,

　　2. It can promote the growth of fibers in different matrices, enhance permeability, improve the circulation of patients' blood system, accelerate metabolism, promote the absorption ability of students' osmotic fluid and the elimination of related inflammation;

　　3, its polyanion has a strong water retention, can improve the water metabolism of the cornea, the cornea has a strong affinity, and can form a breathable water retention film on the surface of the cornea.

　　The most direct way to improve chondroitin sulfate is to eat more chondroitin sulfate. For example, chicken skin, fish skin, shark fin, salmon head, chicken and shark cartilage, we often say, can be wrinkly food.
