Color reactions of Amino Acids
Syed Qizar Afzaal replied to Syed Qizar Afzaal's topic in Organic Chemistry
It's my fault, I should have elaborated the question. For identifying amino acids, one approach is to see the colors they impart with different reagents. All the color reactions which I have studied (Biuret Test, Ninhydrin Test, Xanthoproteic Test, Millon's Reaction, Sakaguchi Reaction) are based on Amino group (-NH2). Why aren't we using Carboxylic Acid (-COOH) group for the color reactions? -
Why only amino (-NH2) group in the amino acid show color reaction? Why not COOH?
