Dipeptides and amino acids do not give this reaction. The name biuret was given to a compound which was produced after urea was heated at 180 c. However using excess alkali it can be removed. Often ammonium and magnesium ions hinder this test. In addition to standard liquid handling. More specifically it tests for presence of peptide bond in a sample.
Add some of the egg white to the biurets solution in the test tube and mix thoroughly while still hand warming.
Under alkaline conditions substances containing two or more peptide bonds form a purple complex with copper salts in the reagent. The co nh bond peptide in polypeptide chain reacts with copper sulphate in an alkaline medium to give a purple colour which can. Add 1 2 ml of the test solution egg albumin and deionized water in the respective test tubes. However using excess alkali it can be removed. The bradford assay is faster and more sensitive. The biuret test is a test that is used to test for proteins.
