1922 J. J. Sudborough Bernthsen's Text-bk. Org. Chem. (new ed.) xiv. 318 Several isomerides of rhamnose are known, e.g. fucose from sea-weed, epifucose, quinovose, rhodeose and isorhamnose.
1965 BioScience 15 584/2 Quinovose has recently been identified as the carbohydrate component of the sulfatide, which accompanies chlorophyll in all plants.
2001 R. V. Stick Carbohydrates vii. 100 Although deoxygenation is possible at any position of a carbohydrate, it is the 6-deoxy sugars that are also widespread—quinovose (6-deoxy- d-glucopyranose), l-rhamnose..and l-fucose..are all constituents of molecules that are found, among other places, in plants and bacteria.
