Deep Learning-Driven Optimization of Antihypertensive Properties from Whey Protein Hydrolysates: A Multienzyme Approach
Bibliographic record
Abstract
This study utilized deep learning to optimize antihypertensive peptides from whey protein hydrolysate. Using the Large Language Models (LLMs), we identified an optimal multienzyme combination (MC5) with an ACE inhibition rate of 89.08% at a concentration of 1 mg/mL, significantly higher than single-enzyme hydrolysis. MC5 (1 mg/mL) exhibited excellent biological stability, with the ACE inhibition decreasing by only 6.87% after simulated digestion. In in vivo experiments, MC5 reduced the systolic and diastolic blood pressure of hypertensive rats to 125.00 and 89.00 mmHg, respectively. MC5 significantly lowered inflammatory markers (TNF-α and IL-6) and increased antioxidant enzyme activity (SOD, GSH-Px, GR, and CAT). Compared to the MC group, the MC5 group showed significantly reduced serum renin and ET-1 levels by 1.25-fold and 1.04-fold, respectively, while serum NO content increased by 3.15-fold. Furthermore, molecular docking revealed four potent peptides (LPEW, LKPTPEGDL, LNYW, and LLL) with high ACE binding affinity. This approach demonstrated the potential of combining computational methods with traditional hydrolysis processes to develop effective dietary interventions for hypertension.

How this classification was reachedexpand
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.
