Chondroitin Sulfate is classified as a type of sulfated, glycosaminoglycan comprising alternating uronic acid and N-acetyl-D-galactosamine residues. They are localized on cell surfaces and in the extracellular matrix, and are important in cell to cell communications. Chondroitin Sulfate A (CSA) consists of an unsulfated glucuronic acid, which is the most abundant in mammalian tissue and is typically extracted from the cartilage of mammals and fish. Chondroitin Sulfate B (CSB), also known as Dermatan Sulfate, which is the most abundant GAG in skin. Chondroitin CS is a purified CSA from porcine trachea. * Defecate high blood fat. * Reduce the risk of Arthralgia. * Relieve certain nerve headache, migraine and atherosclerosis.
