Xanthoproteic Test
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 from yellow to orange.
Thanks alot
Revising tests for tomorrow biochemistry exam
Same here
Doing for class 11 practical
Love this procedure
❤❤
Superbbb
Thank you
thanks a lot I hope more test
You should use gloves, for the manipulation of chimics éléments
