Is it possible to make a quantitative test for protien using biurets test - if so how would you do it? Does it involve titration?

SUMMARY
A quantitative Biuret test for protein determination is feasible and typically involves a colorimetric analysis rather than titration. The test relies on the formation of a complex between copper ions and peptide bonds, resulting in a color change that can be measured spectrophotometrically. The intensity of the color correlates with protein concentration, allowing for quantitative assessment. A brown result may occur due to the presence of high concentrations of protein or interference from other substances.
PREREQUISITES- Understanding of protein chemistry and peptide bonds
