Fig. 2. 3-Nitrotyrosine results from the treatment of L-tyrosine with nitric acid. (A) HPLC<br />

chromatogram of L-tyrosine. (B) HPLC chromatogram of L-tyrosine reacted with nitric acid for<br />

1 h. Inset, absorption spectrum of peak eluting at ~8 min. The prominent peak eluting at 2 min<br />

corresponds to a contaminant in the nitric acid. (C) HPLC chromatogram of 3-nitrotyrosine. Inset,<br />

absorption spectrum of peak eluting at ~8 min. HPLC was accomplished using a Beckman<br />

Ultrasphere obs column (4.6 × 250mm, 5 µm) as previously described (15).
