Chondroitin sulfate (CS) is a glycosaminoglycan naturally present in cartilage, which is highly heterogeneous. It is composed of N-acetylgalactosamine, D-glucuronic acid and sulfate residues, and is often attached to proteins to form proteoglycans. Chondroitin sulfate has a variety of physiological functions, including anti-inflammatory, immunomodulatory, cardiovascular and cerebrovascular protection, neuroprotection, and antioxidant effects.
Chondroitin sulfate is an acidic mucopolysaccharide extracted from healthy domestic animal cartilage or shark cartilage. It is mainly composed of chondroitin sulfate A, C and other types of chondroitin sulfate. It is widely present in animal cartilage, larynx, nasal bones, tendons, ligaments, skin, cornea and other tissues. Chondroitin sulfate mainly exists in the form of chondroitin sulfate sodium salt. Chondroitin sulfate is mainly composed of sodium sulfate copolymerized by N-acetylgalactosamine (2-acetamide-2-deoxy-β-D-pyranose) and D-glucuronic acid. The copolymer is alternately connected by β-1,4 and β-1,3 glycosidic bonds.
◆ Participate in the manufacture of bones-bones are made of calcium and phosphorus. However, amino acids and vitamin D are needed to make bones. Chondroitin sulfate plays an important role in transporting materials or supporting materials to form bones during bone formation.
◆ Maintaining the smoothness of joints - Chondroitin sulfate and hyaluronic acid are the main components of cartilage (27-43%) that are mostly present in joints, giving cartilage elasticity and smoothness. In addition, it is also related to maintaining the elasticity of ligaments or tendons surrounding joints. Hyaluronic acid is the main component of synovial fluid, and both chondroitin sulfate and hyaluronic acid can promote joint smoothness.
Chondroitin sulfate is usually extracted from animal cartilage, and the extraction sources are diverse: cow bones, chicken bones, pig bones, shark bones. It is a natural substance. Compared with some chemically synthesized drugs, it is safer and has relatively fewer side effects.
After a lot of clinical research and practice, it has been proven that chondroitin sulfate can be used for a long time without causing serious adverse effects on the body. This is an important advantage for people who need long-term joint care.
Chondroitin sulfate is a natural component of cartilage that can provide cushioning for joints, alleviate impact and friction during movement, help relieve joint pain and promote cartilage repair.
