| | alpha-L-Rhamnose Usage And Synthesis |
| Chemical Properties | L-Rhamnose has no odor, but has a very sweet taste. | | Chemical Properties | White crystals. For
equilibrium mixture optical rotation is +9.18
degrees. Very soluble in water and in methanol;
soluble in absolute alcohol. | | Uses | Synthetic sweetener research. | | Definition | ChEBI: The acyclic form of L-rhamnose. | | Flammability and Explosibility | Not classified | | Purification Methods | Crystallise 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.] |
