Bismuth germanium oxide or bismuth germanate is an inorganic chemical compound of bismuth, germanium and oxygen.
 Most commonly the term refers to the compound with chemical formula Bi Ge O (BGO), with the cubic evlitine crystal structure, used as a scintillator.
 (The term may also refer to a different compound with formula BiGeO, an electro-optical material with sillenite structure, and Bi Ge O .)
Bismuth pentoxide is a chemical compound containing bismuth and oxygen.
 It is a dark red powder decomposing above 20℃.
 It has the chemical formula BiO.
 It is not known as a pure substance, but is usually mixed with water, bismuth tetroxide or bismuth trioxide.
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.
1,3-Indandione (indanedione) is an organic compound with the molecular formula CHO.
 Chemically, it is a β-diketone.
 In standard conditions it is referred to in different sources as either a colorless or yellowish, green, or (most commonly) yellow solid.
Bismuth(III) acetate is an ionic salt composed of positive bismuth ions and negative acetate ions.
 The bismuth ions have a charge of 3+, while the acetate ions have a charge of 1-.
 Therefore, the empirical formula for bismuth(III) acetate is Bi(AOC).
Bismuth oxynitrate is the name applied to a number of compounds that contain Bi, nitrate ions and oxide ions and which can be considered as compounds formed from BiO, NO and HO.
 Other names for bismuth oxynitrate include bismuth subnitrate and bismuthyl nitrate.
 In older texts bismuth oxynitrate is often simply described as BiONO.
 Bismuth oxynitrate was once called magisterium bismuti or bismutum subnitricum, and was used as a white pigment, in beauty care, and as a gentle disinfectant for internal and external use.
Saponarin is a flavone glucoside.
 It is found in "Saponaria officinalis" and in "Strongylodon macrobotrys" where it imparts the characteristic jade color to the flower.
 This coloration has been shown to be an example of copigmentation, a result of the presence of malvin (an anthocyanin) and saponarin in the ratio 1:9.
 Under the alkaline conditions (pH 7.9) found in the sap of the epidermal cells, this combination produced a blue-green pigmentation; the pH of the colorless inner floral tissue was found to be lower, at pH 5.6.
 Experiments showed that saponarin produced a strong yellow colouring in slightly alkaline conditions, resulting in the greenish tone of the flower.
 It is also found in passion flowers ("Passiflora sp.")
.
Ribose is a carbohydrate with the formula CHO; specifically, it is a pentose monosaccharide (simple sugar) with linear form H−(C=O)−(CHOH)−H, which has all the hydroxyl groups on the same side in the Fischer projection.
Bismutite or bismuthite is a bismuth carbonate mineral with formula Bi(CO)O (bismuth subcarbonate).
 Bismutite occurs as an oxidation product of other bismuth minerals such as bismuthinite and native bismuth in hydrothermal veins and pegmatites.
 It crystallizes in the orthorhombic system and typically occurs as earthy to fibrous masses.
Glucose is a simple sugar with the molecular formula CHO.
 Glucose circulates in the blood of animals as blood sugar.
 It is made during photosynthesis from water and carbon dioxide, using energy from sunlight.
 It is the most important source of energy for cellular respiration.
 Glucose is stored as a polymer, in plants as starch and in animals as glycogen.

Question: What is the name of the simple sugar with the molecular formula CHO that reduces bismuth oxynitrate to bismuth under alkaline conditions?
Answer: Glucose
