Figure 1From: Phenylalanine as a hydroxyl radical-specific probe in pyrite slurriesPotential oxidation pathways of Phe and Tyr isomers. In this study, phenyl hydroxylation of Phe by .OH has been shown to form o-, m-, and p-Tyr. Subsequent degradation of Tyr isomers are the six different isomers of DOPA.Back to article page
