Barfoed’s test is a chemical test used for detecting the presence of monosaccharides. It is based on the reduction of cupric (II) acetate to cuprous (I) oxide (Cu 2 O), which forms a brick-red precipitate.
12 Μαΐ 2018 · Barfoed’s test is used for distinguishing monosaccharides from reducing disaccharides. Monosaccharides usually react in about 1-2 minute while the reducing disaccharides take much longer time between 7-12 minutes to react with the reagent.
18 Απρ 2022 · Principle of Barfoed’s Test. The Barfoed reagent is made up of copper acetate in a dilute solution of acetic acid. Since acidic pH is unfavorable for reduction, monosaccharides, which are strong reducing agents, react in about 1-2 min.
Barfoed's test used to distinguish the monosaccharide and disaccharide. Monosaccharides oxidized by Cu 2+ ions form a carboxylic group and precipitation of copper (I) oxide that has brick red color. A positive results of the test is indicated by the appearance of brick red precipitate.
