Chondroitin sulfate is a mixed acidic mucopolysaccharide extracted from the cartilage of pigs, cattle, chickens, and sharks. It is a white powder at room temperature. It is odorless, odorless, highly absorbent, and easily soluble in water. It is unstable when it is exposed to higher temperature or acid, which is mainly deacetylated or degraded into monosaccharide or polysaccharide with smaller molecular weight.
It has anticoagulant and antithrombotic effects, and is clinically used to treat coronary arteriosclerosis, increased blood lipids and cholesterol, angina pectoris, neuralgia, myocardial ischemia and myocardial infarction. It can also be used to prevent and treat hearing impairment caused by streptomycin, as well as migraine headaches, neuralgia, shoulder pain in the elderly, back pain, arthritis and hepatitis, and skin cosmetics. It is reported that chondroitin sulfate can also effectively repair cartilage and synovium at joints, maintain lubrication between joint cartilage, make it elastic, and improve symptoms such as joint pain and inflammation. It also has special effects on tendons, ligaments, diaphragm cardiovascular and other diseases. Chondroitin sulfate is also one of the important components in the eye tissue. It has the functions of promoting corneal water metabolism, improving microcirculation, protecting the cornea and promoting corneal tissue damage repair. At the same time, it can also form a protective film on the corneal surface to prevent water from spreading. Effectively relieve visual fatigue and dry eye symptoms; in addition to antibacterial and anti-inflammatory, aminoethanesulfonic acid also participates in a variety of physiological activities in the eye tissues to promote metabolism and improve visual fatigue, which is a more important biochemical product on the market.
