APPLICATION |
||
| Glucosamine is the most abundant naturally occurring amino sugar in which one or more nonglycosidic hydroxyl groups are replaced by an amino or substituted amino group. Glucosamine is a glucose substituted at the 2 position. It is present in peptidoglycans and variety of complex polysaccharides such as blood group substances. It is generally acetylated (N-acetylglucosamine). It is the basic structural unit of chitin which is a linear unbranched homopolymer composed of N-acetyl-D-glucosamine residues in beta-linkage (1,4) like cellulose. Chitin is the principal constituent of arthropod exoskeletons to cover the surface of the body, found mainly in crab, lobster or shrimp shell. Chitin is also found in the cell walls of some fungi. Muramic acid is a compound consisting of glucosamine and lactic acid joined by an ether linkage. It is the characteristic polysaccharide composing bacterial cell walls. Chitosan is the de-acetylation form of chitin; a polysaccharide composed of repeating glucosamine units. It is used to absorb heavy metals in water treatment. Chondroitin is a glycosaminoglycan composed of a sulfated (C-4 or C-6) N-acetylgalactosamine residue linked to a glucuronic acid residue. It is the It consists of repeating disaccharide units. It is abundant in connective tissues, particularly in the ground substance of blood vessels, bone, and cartilage. Chondroitin sulfate A is sulfated on C-4 position and called also chondroitin 4-sulfate to dominate the position of the sulfate group on the sugar, while Chondroitin sulfate C is chondroitin 6-sulfate. Chondroitin sulfate B is another name of dermatan sulfate which is sulfated on the C-4 position but also the C-5 of the uronic acid is under the epimerisation of glucuronic acid to iduronic acid. Glucosamine and chondroitin sulfate are being tested for potential benefit in osteoarthritis. They are stabilizd with hydrochloride or sulfur to be used as dietary or nutritional supplements. Glucosamine is believed to contribute to the pain relief of cartilage and structure rebuilding of cartilage in the joint. | ||
