The product is a unique type of linear macromolecular mucopolysaccharide, composing repeating disaccharide units of glucuronic acid and N-acetyl glucosamine. Its chemical formula is (C14H21NO11)n.

SingJoint® , is non-animal original, with the advantages of high viscoelasticity, lubricity, physical alterability and good biocompatibility. It is a medical polymer extracted and refined by high-tech bio-engineering from streptococcal fermentation metabolites. It is sterile, and free from pyrogenicity, allergy, genetic toxicity, or skin irritation. Due to fermentation production of HA, the product has no risk of being a virus carriers and dissemination medium when extracting animal tissues or organs. This product can be used as an orthopedics agent to improve the joint function. When used for injections in joint cavities, due to its macromolecular characteristic and good viscoelasticity, it stimulates synovium to produce high molecular sodium hyaluronate, which is beneficial for releasing joint pain, increasing mobility, decreasing synovitis and delaying progression of disease.
