Glucosamin Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
(β form.) Colorless needles. Mp 110C (decomposes). Very soluble in water; slightly soluble in methanol and ethanol; insoluble in ether and chloroform.Occurrence
Glucosamine is found in mucopolysaccharides, chitin, and mucoproteins. Glucosamine is a naturally occurring substance; glucosamine sulfate is manufactured synthetically.Verwenden
Glucosamine is an amino sugar that can regulate growth factor gene transcription. It is also widely touted as remedy for osteoarthritis (OA).Definition
ChEBI: The open-chain form of D-glucosamine.Weltgesundheitsorganisation (WHO)
Glucosamine is found in chitin, mucoproteins and mucopolysaccharides. It is used as a pharmaceutical aid. Glucosamine sulfate has been used in the treatment of rheumatic disorders though it is not widely marketed for this purpose.l?uterung methode
Crystallise the amines from MeOH. The free base has been obtained from the hydrochloride (21.5g, see below) in a mixture of Et3N (15mL) and EtOH (125mL) by shaking for 2days at room temperature, and the solid Et3N.HCl is filtered off and the process repeated with more Et3N (3-4 times) until the D-glucosamine (15g) is free from Cl ions. It has m 88o , [] D20 +100o mutarotating to +47.5o (c 1, H2O). When Et2NH is used as base, the to conversion is complete giving D-glucosamine. The pentaacetate is purified by dissolving in CHCl3, treating with charcoal, drying (MgSO4), evaporating the solvent, and adding a little dry Et2O to induce crystallisation. It has m 124-126o, [] D +113o (c 1, CHCl3) after 16hours in a desiccator. [Leaback Biochemical Preparations 10 118 1963.] The N-acetyl derivative, m 203-205o from MeOH/Et2O (dry in vacuum P2O5) has [] D +75o to +41o (c 2, H2O); this derivative can also be purified by dissolving in the minimum volume of H2O to which is added 7-8volumes of EtOH followed by Et2O until turbid and keeping at ~20o to crystallise. Wash the crystals with MeOH then Et2O and dry in vacuo over P2O5. [Horton Biochemical Preparations 11 1 1966.]Glucosamin Upstream-Materialien And Downstream Produkte
