When a protein test turns purple, it typically indicates the presence of protein in the sample being tested. This color change is commonly associated with the Biuret test, where proteins react with copper ions in an alkaline solution, resulting in a purple complex. The intensity of the purple color can reflect the concentration of protein present. This test is often used in laboratories to assess protein levels in various biological samples.

What color will a peptide bond be after using the Biuret test?
in biuret test the presence of peptide bonds gives a violet color. but it should be noted that a minimum of two peptide bonds should be present in the protein to get a positive answer to this test.

What is formed when cuso4 n naoh are used for protein test?
When CuSO4 and NaOH are used for the protein test (Biuret test), the formation of a purple-colored complex indicates the presence of proteins. This color change occurs due to the interaction of the copper ions in CuSO4 with the peptide bonds in proteins, leading to the formation of a coordination complex that absorbs light in the visible range.

How do you test for proteins?
Proteins can be tested for using various methods including Western blotting, enzyme-linked immunosorbent assay (ELISA), and protein assays such as Bradford or BCA assays. These tests rely on specific interactions between proteins and antibodies or colorimetric changes to detect and quantify protein levels.
What is the change in color in testing for the presence of protein in egg albumin using solution sodium hydroxide and copper sulfate?
Copper sulphate when mixed with a protein will turn purple if the amount of protein is sufficient enough in quantity to trigger the reaction. Planex1234 says; No offense but i think it is starch that turns dark blue - purple. Thetada says: the colour changes are arguably similar. Iodine solution goes blue/black in the presence of starch. The colour that sodium hydroxide / copper sulphate solution goes in the presence of protein is variously described as mauve / purple.
