https://en.wikipedia.org/wiki/Biuret_test
WebIn 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.
