D-Glucosamine Sulfate CAS No 29031-19-4

Details:

Product Description
 Glucosamine (C6H13NO5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of the polysaccharides chitosan and chitin, which compose the exoskeletons of crustaceans and other arthropods, as well as the cell walls of fungi and many higher organisms. Glucosamine is one of the most abundant monosaccharides.It is produced commercially by the hydrolysis of crustacean exoskeletons or, less commonly, by fermentation of a grain such as corn or wheat.
Evidence for the effectiveness of glucosamine supplements is mixed. In the United States, it is one of the most common non-vitamin, non-mineral, dietary supplements used by adults.

Function

By stimulating the biochemical synthesis of mucopolysaccharide and increasing the intake of calcium in bone and cartilage, the metabolic function and nutrition of bone and cartilage tissue can be improved, the consistency of synovial fluid can be improved, the syntheses of synovial fluid can be increased, and the lubrication function of joint can be provided. This product can block the pathological process of osteoarthritis, prevent and cure the progress of disease, improve the function of joint movement, alleviate joint pain, inhibit and subside. Joint degeneration.
