Abstract
A series of ferrocene-containing collagen models Fc-CO-(Pro-Hyp-Gly)n-Cys (n = 4 (1), 6 (2), 7 (3), 8 (4), 9 (5)) were synthesized by solid-phase synthesis. Biophysical studies using circular dichroism (CD) show that these collagen analogues form triple-helical conformations, and the peptides showed a range of thermal stabilities ((T(m)), 38-74 degrees C). Results also indicate that the ferrocene (Fc)-labeled collagen models possesses a higher triple-helical propensity than the unlabeled collagen models as demonstrated by the higher melting temperatures and thermodynamic parameters, and we conclude that the Fc group at the N-terminal position of the peptide strands increases the stability of the triple helix.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
