In chemistry, the Biuret test (IPA: / ˌbaɪjəˈrɛt /, / ˈbaɪjəˌrɛt / [1] ), also known as Piotrowski's test, is a chemical test used for detecting the presence of at least two peptide bonds in a molecule. In the presence of peptides, a copper (II) ion forms mauve -colored coordination complexes in an alkaline solution.

Mar 3, 2023 · Biology definition: A Biuret test is used for detecting compounds with peptide bonds. A biuret reagent may be used to test the aqueous sample. Thus, the biuret test is used to detect proteins. That is because proteins are made up of polypeptides, which in turn, are made of amino acids joined by peptide bonds.
