Objective:
this test is used to differentiate aromatic amino acids
which give positive result from other amino acids
Principle:
Xanthoproteic test is used to detect amino acids
containing an aromatic nucleus (tyrosine,
tryptophan and phenylalanine) in a protein
solution which gives yellow color nitro derivatives on
heating with conc. HNO3. The aromatic benzene ring undergoes
nitration to give yellow colored product. Phenylalanine gives
negative or weakly positive reaction though this amino acid
contains aromatic nucleus because it is difficult to nitrate
under normal condition. On adding alkali to these nitro
derivative salts, the color change fro yel...
