Are all amino acids reactive with the Biuret reagent?

Not all amino acids react with the Biuret reagent. The Biuret test specifically detects the presence of peptide bonds, which are formed when amino acids link together in proteins. Therefore, free amino acids without peptide bonds do not produce a color change with the Biuret reagent. However, when amino acids are part of a polypeptide or protein, they will react positively with the Biuret test.
