Hydrin three ketone reaction

Alpha-amino acids and ninhydrin were co-heated in weak acidic solution, then dehydrated and decarboxylated to form aminolidine-ninhydrin, and then reacted with hydrated ninhydrin to form purple red and finally blue substance. This color reaction is often used for colorimetric determination of alpha amino acids and chromogenic analysis.
