L(+)-Rhamnose monohydrate Usage And Synthesis
  • Chemical PropertiesWhite crystals or crystalline powder
  • UsesComposition of plum leaf polysaccharides.
  • UsesL-Rhamnose monohydrate is a deoxy sugar in plants and bacteria. It is a component of plant cell walls that helps maintain structure. L-Rhamnose monohydrate is used as a starting material for the production of furanones. It is an important material involved in the reaction of flavors developed during the preparation of various foods like bread, grilled meats, etc.
  • Biological FunctionsL-Rhamnose is a part of plant cell wall polysaccharides, rhamnogalacturonan I and rhamnogalacturonan.It is also present in bacterial cell walland a major antigenic determinant contributing to its pathogenicity.L-rhamnose is non-absorbable in humans but is fermented by intestinal microbes. Supplementation of L-rhamnose slows down gastric emptying. L-rhamnose monosaccharide conjugated immunogens have applications in cancer immunotherapies. Intake of L-rhamnose elevates serum propionate levels.
    L-Rhamnose monohydrate has been used:
    in biofilm enhancement assay in S.pneumonia.
    as a sugar drink in humans undergoing intestinal barrier permeability test.
    for the standard curve generation in high performance liquid chromatography(HPLC).
  • Purification MethodsCrystallise the rhamnose from H2O or EtOH. It crystallises easily as the monohydrate by evaporating a solution in MeOH (90%) and H2O (10%). It is also purified by dissolving in a small volume of EtOH, adding a few drops of H2O and cooling. 1H NMR in D2O at 44o contains 60% -pyranose and 40% -pyranose forms [Angyal Adv Carbohydr Chem 42 15 1984.] [Smith J Chem Soc 1035 1940, McGeachin & Beevers Acta Cryst 10 227,230 197, Beilstein 1 IV 4261.]
