The preparation of dyes from aromatic amines. Aromatic amines, such as phenylamine, are important industrially for the production of dyes. Modern dyes are formed in a two-stage synthesis: WebThe Amino Acids. Proteins are formed by polymerizing monomers that are known as amino acids because they contain an amine (-NH 2) and a carboxylic acid (-CO 2 H) functional group. With the exception of the amino acid proline, which is a secondary amine, the amino acids used to synthesize proteins are primary amines with the following … crystallisation funds
