Chondroitin Sulfate Extracted from Bovine cartilage
pointchem biotech limited china [China] 
Chondroitin Sulfate is a sulfated Glycosaminoglycan composed of a chain of alternating sugars (N-Acetylgalactosamine and Glucuronic acid). It is one of the main components of cartilage and mucosa layers, forming the connective tissue that holds muscles, nerves and blood vessels together. It is used as a dietary supplement to support cartilaginous tissues and combat various forms of arthritis in humans and animals.
