Skin sulfate is just one of chondroitin sulfate, also known as chondroitin sulfate B.

　　The following help you analyze:

　　Firstly, chondroitin sulfate is an acidic mucopolysaccharide extracted from cartilage such as trachea of mammals. White powder, odorless, tasteless, hygroscopic, soluble in water, insoluble in ethanol and acetone and other organic solvents, when water is swelling or into a viscous pulp, more unstable to heat. Keep sealed away from light. Chondroitin is a mucopolysaccharide composed of d-glucuronic acid and n-acetyl-d-galactosamine. Chondroitin sulfate is the sulfate of chondroitin and constitutes the main component of connective tissue. It clarifies lipids, improves detoxification, diuresis and analgesia. It is very effective for collagenic disorders and also for hearing impairment caused by streptomycin. Sodium salt is a hygroscopic powder, soluble in water, but insoluble in ethanol and acetone. Acidic mucopolysaccharide is one of the unique components in the connective tissue matrix in vivo. Chondroitin sulfate A is one of the acidic mucopolysaccharides. It is from disaccharide to polymerize and become macromolecule poly polysaccharide. For the prevention and treatment of coronary heart disease.

　　Sulfate skin element: also known as sulfate skin, chondroitin sulfate B. One of the amino polysaccharides. The molecular weight is about 20,000 ~ 50,000. Optical rotation [alpha] d-55 ° ~ -63°(water). It mainly exists in the skin, blood vessels, heart valves, ligaments and other parts, and is formed by the repeated occurrence of disaccharide units consisting of eduronic acid and 4-acetylgalactose sulfate.

　　In addition, chondroitin sulfate is mainly extracted from pancreatic, liver, lung, cartilage, fish scales and shark organs, including chicken, pig and cow tissues, while dermal sulfate is only extracted from pig skin and cow lungs.

　　So, both belong to polysaccharide, only chondroitin sulfate B is called skin sulfate. Hope to help you!
