Table 1.
Serum protein amino acid M + 1 enrichments
| Amino Acid | M + 1 Enrichment (E[M + 1]), % | No. of 2H in Amino Acid (nH) |
|---|---|---|
| Alanine | 20.63 ± 0.13 | 3.97 ± 0.13 |
| Glycine | 9.23 ± 0.10 | 1.78 ± 0.06 |
| Valine | 3.57 ± 0.05 | 0.69 ± 0.02 |
| Leucine | 4.80 ± 0.05 | 0.92 ± 0.03 |
| Proline | 6.21 ± 0.08 | 1.19 ± 0.04 |
| Serine | 11.50 ± 0.13 | 2.21 ± 0.08 |
| Phenylalanine | 2.26 ± 0.10 | 0.44 ± 0.02 |
Values are means ± SE. The M + 1 enrichments of selected serum protein amino acids were measured in samples obtained weekly from days 14 through 42. The number of deuteriums in each amino acid was calculated by dividing the average M + 1 enrichment shown in the table by the mean water enrichment at steady state (E2H2O = 5.20 ± 0.17%).
