  2. Benedict's reagent - Wikipedia

    en.wikipedia.org/wiki/Benedict's_reagent

    Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]

  3. Fehling's solution - Wikipedia

    en.wikipedia.org/wiki/Fehling's_solution

    In organic chemistry, Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone (>C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849. [1]

    en.wikipedia.org/wiki/Reducing_sugar

    It reacts with a reducing sugar to form 3-amino-5-nitrosalicylic acid, which can be measured by spectrophotometry to determine the amount of reducing sugar that was present. [8] Some sugars, such as sucrose, do not react with any of the reducing-sugar test solutions. However, a non-reducing sugar can be hydrolyzed using dilute hydrochloric acid ...

  9. Aldonic acid - Wikipedia

    en.wikipedia.org/wiki/Aldonic_acid

    Aldonic acids are the products of the oxidation of aldoses by Benedict's or Fehling's reagents. [7] Copper ions react with an aldose to form a red precipitate, Cu 2 O. The reaction scheme of an aldose being oxidized by the copper ions in a Benedict's reagent solution. The R group provided is an example of a sugar backbone.
