WebMar 24, 2024 · Protein Detection Theory: Proteins can be detected through the use of the Biuret test.Specifically, peptide bonds (C-N bonds) in proteins complex with Cu 2+ in Biuret reagent and produce a violet color. A Cu 2+ must complex with four to six peptide bonds to produce a color; therefore, free amino acids do not positively react. Long … WebThe normal color of biuret reagent is blue. The reagent turns violet in the presence of peptide bonds -- the chemical bonds that hold amino acids together. The proteins detected must have at least three amino acids, which means that …
