rhamnose [′ram‚nōs]
(biochemistry) C6H12O5A deoxysugar occurring free in poison sumac, and in glycoside combination in many plants. Also known as isodulcitol. Rhamnose (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. Want to thank TFD for its existence?

Biochemical Characteristics All the isolates were examined for the following biochemical characteristics: oxidase production, urease production, Methyl Red and Vogues Proskauer test, indole production, citrate production, arginine dehydrolase, lysine decarboxylase, ornithine decarboxylase, gluconate, malonate, acid production from arabinose, dulcitol, glucose, lactose, maltose, mannitol, raffinose, rhamnose, sorbitol, sucrose, trehalose, and xylose (MacFaddin, 1980). Following total acid hydrolysis of the polysaccharide fraction with TFA, the sugar components were analyzed using TLC and the resultant chromatogram indicated the presence of six monosaccharides, including glucose, galactose, arabinose, xylose, rhamnose and glucuronic acid, according to the spots matching with corresponding monosaccharide standards. Effects of the polysaccharide fraction of Urtica fissa on castrated ... by Zhang, Q.; Li, L.; Liu, L.; Li, Y.; Yuan, L.; Song, L.; Wu, Z. / Phytomedicine: International Journal of Phytotherapy & Phytopharm |
