Description
Barfoed’s reagent is a chemical solution commonly used in laboratory settings to test for the presence of monosaccharides, specifically reducing sugars such as glucose, fructose, and galactose. It consists of a mixture of copper(II) acetate and acetic acid. When heated in the presence of a monosaccharide, such as glucose, a red precipitate of copper(I) oxide forms, indicating a positive result for the presence of reducing sugars.
