The Biuret solution is made of copper sulfate and sodium hydroxide. In fact, the copper ions, in alkaline environment, form a complex with the peptide bonds in proteins, resulting in a change in color from blue to violet.The food we often use for this test is eggs albumen (powder). If you want to test a solid food remember to crush it first, and then to add distilled water in order to obtain a food solution. #biochemistry #biologymemes #stem
