Studies on the Interaction between Procyanidins and Bovine Serum Albumin by Fluorescence Spectroscopy
Bibliographic record
Abstract
The interaction between procyanidins(PC) and bovine serum albumin(BSA) in physiological buffer(pH=7.4) was studied by fluorescence spectroscopy.The quenching constants were obtained at 295 K,303 K,310 K and 315 K.The results indicated that the fluorescence quenching mechanism for BSA through procyanidins binding is likely a static quenching process.The thermodynamic parameters,enthalpy change(△rHm) and entropy change(△rSm),were calculated to be 38.282 kJ·mol-1,and 215.9656 kJ·mol-1,respectively,which indicated that the interaction of procyanidins with BSA was driven mainly by hydrophobic force.The process of binding was a spontaneous process in which Gibbs free energy change(△rGm) was negative.The effect of procyanidins on the conformation of BSA was analyzed using synchronous fluorescence spectroscopy.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
