L-Xylose, CAS:609-06-3

L-XyloseL-Xylose is a sugar first isolated from wood, and named for it. Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional group. It is derived from hemicellulose, one of the main constituents of biomass. Like most sugars, it can adopt several structures depending on conditions. With its free aldehyde group, it is a reducing sugar.CAS Number609-06-3Product NameL-xyloseIUPAC Name(2S,3R,4S)-2,3,4,5-tetrahydroxypentanalMolecular FormulaC5H10O5Molecular Weight150.13 g/molInChIInChI=1S/C5H10O5/c6-1-3(8)5(10)4(9)2-7/h1,3-5,7-10H,2H2/t3-,4+,5+/m1/s1InChI KeyPYMYPHUHKUWMLA-WISUUJSJSA-NSMILESC(C(C(C(C=O)O)O)O)OSolubilitySoluble in DMSOSynonymsL-Xylose; L(+)-Xylose; EINECS 210-174-1; NSC 26213; NSC-26213; NSC26213;Canonical SMILESC(C(C(C(C=O)O)O)O)OIsomeric SMILESC([C@@H]([C@H]([C@@H](C=O)O)O)O)OCOA:
