Barfoed’s test is a chemical test used for detecting the presence of monosaccharides. It is based on the reduction of copper(II) acetate to copper(I) oxide (Cu2O), which forms a brick-red precipitate.

Why do monosaccharides give Barfoed tests?

… Barfoed’s test can be used to detect the monosaccharides (reducing sugar) in the presence of di-and polysaccharides under acidic conditions (39) . This is because of only monosaccharides can react faster in the lower pH environment to give a positive result. …
