Chondroitin sulfate (CS) is a class of glycosaminoglycans that are covalently linked to proteins to form proteoglycans. Chondroitin sulfate is widely distributed in the extracellular matrix and cell surface of animal tissues. The sugar chain is composed of alternating glucuronic acid and N-acetylgalactosamine (also known as N-acetylgalactosamine) disaccharide units. The linker region is attached to a serine residue of the core protein. The sources of chondroitin produced by the company are cattle, fish, chicken, shark, etc., which can be customized by customers to meet the professional needs of different customers.

Chondroitin sulfate is a chemical normally found in the cartilage around the joints of the human body. Chondroitin sulfate is manufactured from animal sources, such as bovine cartilage. Chondroitin sulfate is an important structural component of cartilage and provides cartilage resistance to compression. Like glucosamine, chondroitin sulfate has become a widely used dietary supplement for the treatment of osteoarthritis.
