Polypeptides having cholesterol-lowering function in soybean protein hydrolysate, preparation method thereof, and uses thereof

Abstract

The present disclosure provides polypeptides having a cholesterol-lowering function in a soybean protein hydrolysate, a preparation method thereof, and uses thereof. The polypeptides are derived from peptide fragments having a molecular docking “binding energy” value of less than −1.2 kcal with cholesterol esterase. The peptide fragments of the polypeptides that are subjected to molecular docking with cholesterol esterase are derived from 23 polypeptides having a Peptide Ranker bioactivity score of greater than 0.9. The polypeptides possess a significant blood-lipid-lowering function.
