摘要：
Aliphatic amino acids are smoothly oxidized by peroxomonophosphoric acid (PMPA) in the pH region 6-10. Kinetic studies reveal second order dependence in the amino acid not observed hitherto in any of the PMPA oxidations. Dependence in PMPA is unity. Rate-pH profile yields a maximum around pH 8. The reaction path includes oxidation steps due to H2PO5- and HPO5(2-). Second order dependence in the amino acid has been attributed to participation of two Zwitter-ionic molecules of the amino acid to form a nucleophile.
