D-Glucosamine, Cas:90-77-7

D-Glucosamine,Glucosamine, also known as dona S or hespercorbin, belongs to the class of organic compounds known as hexoses. These are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. Glucosamine is soluble (in water) and a very weakly acidic compound (based on its pKa). Within the cell, glucosamine is primarily located in the cytoplasm. Glucosamine exists in all eukaryotes, ranging from yeast to humans. Glucosamine participates in a number of enzymatic reactions. In particular, glucosamine can be biosynthesized from beta-D-glucose. Glucosamine can also be converted into beta-muramic acid. Outside of the human body, glucosamine can be found in common bean, green bean, and yellow wax bean. This makes glucosamine a potential biomarker for the consumption of these food products.Chitosan is an aminoglycan consisting of beta-(1->4)-linked D-glucosamine residues. It has a role as a plant activator and a Saccharomyces cerevisiae metabolite. It is an aminoglycan and an exopolysaccharide. It is a conjugate base of a cationic chitosan.CAS Number90-77-7Product Namebeta-D-GlucosamineIUPAC Name(2R,3R,4R,5S,6R)-3-amino-6-(hydroxymethyl)oxane-2,4,5-triolMolecular FormulaC6H13NO5Molecular Weight179.17 g/molInChIInChI=1S/C6H13NO5/c7-3-5(10)4(9)2(1-8)12-6(3)11/h2-6,8-11H,1,7H2/t2-,3-,4-,5-,6-/m1/s1InChI KeyMSWZFWKMSRAUBD-QZABAPFNSA-NSMILESC(C1C(C(C(C(O1)O)N)O)O)OCanonical SMILESC(C1C(C(C(C(O1)O)N)O)O)OIsomeric SMILESC([C@@H]1[C@H]([C@@H]([C@H]([C@@H](O1)O)N)O)O)O
