What is the name of the simple sugar with the molecular formula CHO that reduces bismuth oxynitrate to bismuth under alkaline conditions?
Nylander's test Nylander's test is a chemical test used for detecting the presence of reducing sugars. Glucose or fructose reduces bismuth oxynitrate to bismuth under alkaline conditions. When Nylander's reagent, which consists of bismuth nitrate, potassium sodium tartrate and potassium hydroxide, is added to a solution with reducing sugars, a black precipitate of metallic bismuth is formed.
Allose Allose is an aldohexose sugar. It is a rare monosaccharide that occurs as a 6-O-cinnamyl glycoside in the leaves of the African shrub "Protea rubropilosa". Extracts from the fresh-water alga "Ochromas malhamensis" contain this sugar but of unknown absolute configuration. It is soluble in water and practically insoluble in methanol.
