WebFeb 16, 2024 · The biuret test is a test that is used to test for proteins. More specifically, it tests for presence of peptide bond in a sample. According to Janiro, Sy, Yap, Llanos-Lazaro and Robles (78), the biuret test is one of the earliest methods that have been developed for determining protein content. WebFeb 18, 2024 · Biuret reagent is a blue-coloured alkaline solution commonly used in the Biuret Test for Protein. It is made up of a mixture of copper sulphate (CuSO 4 ) and potassium hydroxide (KOH) in water. The copper ions in the reagent react with the peptide bonds in proteins to form a violet-coloured complex.

WebThe objective in this experiment was to identify the presence of macromolecules in twelve samples using the iodine test, the Benedict test, and the biuret test. In the iodine test, starch and glycogen are the polysaccharides that can be identified if the test is done properly, (Harisha, 2006). WebApr 7, 2024 · The Biuret test is useful in the identification of proteins and protein estimation. Biuret is a kind of chemical that is formed when urea gets heated to 180 ℃. During this reaction, two molecules of urea tend to condense and form a biuret or a bi-urea molecule. The biuret reagent forms a complex of violet colour in the presence of copper ions. WebThis test can be used for the identification of proteins and also for protein estimation. Biuret is the chemical product formed when urea is heated to 180 o C.
