C6H12O5 A deoxysugar occurring free in poison sumac, and in glycoside combination in many plants. Also known as isodulcitol.
(6-deoxy-L-mannose), a monosaccharide with the general formula C6Hl2O5 that exists in the optically active forms D-rhamnose, L-rhamnose, and racemate. Rhamnose is readily soluble in water and alcohol and participates in reactions that are characteristic of reducing sugars. The L-isomer occurs free in plants and also as a component of many plant and bacterial polysaccharides and plant glycosides. The D-isomer is only present in certain microorganic glycosides and polysaccharides.
