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.
Isomaltulose Isomaltulose is a disaccharide carbohydrate composed of glucose and fructose linked by an alpha-1,6-glycosidic bond (chemical name: 6-"0"-α--glucopyranosyl--fructose). It is present in honey and sugarcane extracts. It tastes similar to sucrose (table sugar) with half the sweetness. Isomaltulose is also known by the trade name Palatinose, which is manufactured by enzymatic rearrangement (isomerization) of sucrose from beet sugar. The enzyme and its source were discovered in Germany in 1950. After evaluation of its basic physiology—reviewed—it has been used as a sugar alternative in foods in Japan since 1985, in the EU since 2005, in the US since 2006, and in Australia and New Zealand since 2007, besides other countries worldwide. Characterization, purity, and analytical methods for commercial isomaltulose are laid down, for example, in the Food Chemicals Codex. Physical and physiological properties of isomaltulose have been summarized; its physical properties closely resemble those of sucrose, making it easy to use in existing recipes and processes.
