The impact of resveratrol on fibril contour lengths and secondary structure probed by FTIR
| Contour length (nm) | FTIR β-sheets position (±2 cm−1) and content (%) | FTIR α-helix position (±2 cm−1) and content (%) | |
|---|---|---|---|
| HEWL | 640 [421:964] | 1626 (29%) | 1656 (3%) |
| HR1 | 445 [234:755] | 1626 (39%) | 1656 (9%) |
| HR2 | 300 [155:577] | 1624 (40%) | 1656 (10%) |
| Insulin | 247 [151:391] | 1630 (32%) | 1658 (7.5%) |
| IR1 | 242 [153:412] | 1627, 1631 (28%) | 1658 (18%) |
| IR2 | 218 [143:352] | 1627 (34%) | 1658 (18%) |
The positions of the β-sheets bands extracted from FTIR spectra of HEWL, HR1, HR2, insulin, IR1, IR2 fibrils solutions together with the associated contour length distribution. The 25th and the 75th percentiles of the distribution are indicated in squared brackets.
