Biuret test
A common chemical test for proteins is the Biuret test. This test involves adding a solution of copper sulfate and sodium hydroxide to the protein sample, resulting in a color change from blue to purple if proteins are present. The intensity of the purple color can provide an estimate of the protein concentration in the sample.
Biuret test
To test for protein. Biuret or solutions of sodium hydroxide and copper sulfate. Tested with a dropper a + result will be purple or something
A positive test for protein typically appears as a violet or purple color when using chemical indicators such as Biuret reagent. This color change indicates the presence of proteins in the test sample.
Common lab tests used to test for the presence of protein include a serum protein electrophoresis (SPEP) test, a urine protein test, and a total protein test. These tests can help diagnose conditions such as kidney disease, liver disease, or protein deficiencies.
Proteins are chemical compounds, not reactions.
One can test for protein in a sample by using a method called the Biuret test. This test involves adding a reagent to the sample, which causes a color change if protein is present. The intensity of the color change can indicate the amount of protein in the sample.
T protein = Total protein

Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
