Xanthoproteic test is a biochemical test[1] for the detection of amino acids[2] containing phenolic or indolic groups like phenylalanine, tyrosine, and tryptophan (aromatic amino acids). The test is named Xanthoproteic test due to the formation of a yellow precipitate of xanthoproteic acid. The term ‘Xantho’ refers to ‘yellow’, so the test is often termed as the Yellow Protein Test. The test gives a positive result for amino acids containing benzene rings or other aromatic groups. The test is a qualitative test that provides information only on the presence or absence of the amino acids.
