13C labeling percentages of silk samples from N. edulis
| AA | DOQSY, 1-13C Ala, % | DOQSY, 1-13C Gly, % | DECODER, 1-13C Ala, % | DECODER, 1-13C Gly, % | Relative abundance of amino acids, % |
|---|---|---|---|---|---|
| Ala | 27.2 (17) | 10.0 (7) | 11.8 (6) | 10.1 (24) | 29 |
| Gly | 3.9 (10) | 59.4 (2) | 1.9 (6) | 48.1 (23) | 40 |
| Pro | 1.9 (1) | 1.6 (8) | 1.6 (6) | 1.4 (4) | 3 |
| Tyr | −1.1 (23) | −1.0 (25) | −1.0 (19) | 1.5 (5) | 4 |
| Glu | 4.0 (9) | 3.5 (2) | 1.9 (3) | 2.9 (4) | 10 |
The absolute labeling degree of the five most abundant amino acids in silk is given in percentage, together with the relative abundance of the respective amino acids in molar percentage. The title of each column refers to the experiment and the intended labeling. SDs are given in brackets.
