Table 2.
Effect of concentration of single amino acids or an amino acid mixture (FAA-mix) on the yield of NO2− measured spectrophotometrically. Coefficient of determination (r2), mean yield (± 1sd) and change in yield with increasing concentration (Slopeyield) are presented. Data are from single amino acids (n = 2) and the FAA-mix (n = 4) for concentrations ranging from 10 to 60 μM.
| Compound | r2 | % Yield |
|---|---|---|
| Glycine | 0.992 | 62 ± 8 |
| Alanine | 0.984 | 52 ± 4 |
| Leucine | 0.970 | 58 ± 6 |
| Valine | 0.992 | 66 ± 5 |
| Lysine | 0.900 | 28 ± 4 |
| FAA-mix | 0.996 | 41 ± 6 |
