Exploring the Novel Pancreatic Lipase-Inhibitory Peptides in Chlorella pyrenoidosa: Preparation, Purification, Identification, and Molecular Docking

Obesity is a worldwide problem, and lowering pancreatic lipase (PL) activity is an effective strategy to counteract it. In this study, pancreatic lipase-inhibitory (PL-I) peptides were isolated and purified from Chlorella pyrenoidosa protein hydrolysates (CPPHs) using ul- trafiltration and Sephadex gel chromatography (Sephadex G-25). A total of 858 peptides were identified by liquid chromatography–tandem mass spectrometry (LC-MS/MS). Four novel PL-I peptides (FLSQPF, VWTPI, IVGPF, and IPYPL)...
