Chondroitin disaccharide di-0S sodium salt

Chondroitin disaccharide di-0S sodium salt ;
2-Acetamido-2-deoxy-3-O-(b-D-gluco-4-enepyranosyl uronic acid)-D-galactose sodium salt; GlcAb(1-4)GalNAc; ?-?UA-[1?3]-GalNAcChondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans.The structural analysis of chondroitin disaccharide di-0S sodium salt has been done by a bacterial enzyme, which is an enzyme that catalyzes the hydrolysis of glycosidic bonds. The reaction mechanism is spontaneous and the biochemical analysis indicates that the molecule is a glycosidic bond with hemiketal and hydration. The active site residues are found to be water molecule, which help in binding with the substrate to form a hemiketal. Biochemical analysis of this molecule reveals that it is an oligosaccharide with two sugar molecules linked by glycosidic bond.CAS Number136132-69-9Product NameChondroitin disaccharide di-0S sodium saltIUPAC Namesodium;(3R,4S)-2-[(3R,4R,5R,6R)-3-acetamido-2,5-dihydroxy-6-(hydroxymethyl)oxan-4-yl]oxy-3,4-dihydroxy-3,4-dihydro-2H-pyran-6-carboxylateMolecular FormulaC14H20NNaO11Molecular Weight401.3 g/molInChIInChI=1S/C14H21NO11.Na/c1-4(17)15-8-11(10(20)7(3-16)24-13(8)23)26-14-9(19)5(18)2-6(25-14)12(21)22;/h2,5,7-11,13-14,16,18-20,23H,3H2,1H3,(H,15,17)(H,21,22);/q;+1/p-1/t5-,7+,8+,9+,10-,11+,13?,14?;/m0./s1InChI KeyKINMCWVHKALKTM-YKBJBWNUSA-MSMILESCC(=O)NC1C(C(C(OC1O)CO)O)OC2C(C(C=C(O2)C(=O)[O-])O)O.[Na+]Canonical SMILESCC(=O)NC1C(C(C(OC1O)CO)O)OC2C(C(C=C(O2)C(=O)[O-])O)O.[Na+]Isomeric SMILESCC(=O)N[C@@H]1[C@H]([C@H]([C@H](OC1O)CO)O)OC2[C@@H]([C@H](C=C(O2)C(=O)[O-])O)O.[Na+]
