Proline. Synopsis. Proline is unique among the amino acids because it is not a primary amino acid (only one carbon bonded to the amine nitrogen), but rather is a secondary amino acid, sometimes called an imino acid.nlike the primary amino acids, free proline is a secondary amine with the side chain curving back from the alpha carbon to bond to the amine nitrogen. When incorporated into a protein, proline therefore lacks an amide proton and locks the phi backbone angle into the static conformation of the pyrrolidine ring.
