Antioxidant and Calcium Binding Activities of Hydrolyzed Oat Bran Proteins and Chromatographic Fractions
Bibliographic record
Abstract
Interest in peptides as bioactive agents has gained attention. Oats are a source of dietary fibers and phenols with demonstrated health benefits. However peptides have received little attention. In this research, oat bran treated with viscozyme and digested with protamex. The hydrolysates separated on RP-HPLC to eight fractions. The fractions were assayed for their ability to scavenge radicals, chelate metals, inhibit peroxide and bind calcium. In ORAC assay, F7 had the highest peroxyl quenching activity compared to OPH and other fractions. In the superoxide radical assay F3 and F6-F8 had higher activities while in the hydroxyl radical assay, F4, F7, F8 were the highest (14-16%).In the metal chelation assay F1 and OPH had the best iron chelating in comparison to the RP-HPLC derived peptides (1.22–22.8%). The calcium binding activity of OPH and peptides F5 and F7 was weak. Spectrums/MS charged peaks in F5 and F7 revealed a number peptides.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
