Product description:

Chondroitin sulfate (CS) is a group of glycosaminoglycans covalently attached to proteins to form proteoglycans. Chondroitin sulfate is widely distributed in the extracellular matrix and cell surface of animal tissues. The sugar chain consists of alternating glucuronic acid and n-acetylgalactosamine (also known as n-acetylgalactosamine) disaccharide units, which are connected to the serine residues of core proteins through a sugar-like linkage

Chondroitin in shark cartilage has an anti-tumor effect.In addition, chondroitin sulfate is also used in cosmetics and wound healing agents.Chondroitin sulfate is an acid mucopolysaccharide, is one of the important components in the eye tissue, has promoted the corneal water metabolism and improvement, suitable for visual fatigue, dry eye disease.


1. The main application approach in medicine is as a drug for the treatment of joint diseases, which can be used in combination with glucosamine to relieve pain and promote cartilage regeneration, thereby fundamentally improving joint problems.Structural improvement

2. Chondroitin sulfate has a protective effect on corneal collagen fibers, which can promote the growth of fibers in the matrix, enhance permeability, improve blood circulation, accelerate metabolism, and promote the absorption of osmotic fluid and the elimination of inflammation.Its polyanion has strong water retention, can improve the water metabolism of cornea tissue, has a strong affinity to cornea, can form a layer of breathable water retention film on the surface of cornea, improve dry eye symptoms.By promoting the formation of stroma, it provides a framework for the migration of cells, which is conducive to the migration of corneal epithelial cells, thus promoting the healing of corneal wounds, the absorption of exudate and the elimination of inflammation.
