When HepG2 cells were treated with IASAEPTVH, LSTSEENSKK, and TEDELQDK at a concentration of 400 µM, the highest inhibitory activities against α-glucosidase were observed, with inhibitory rates of 76.18% ± 2.10%, 71.94% ± 2.00%, and 70.54% ± 1.76%, respectively. Furthermore, IASAEPTVH, LSTSEENSKK, and TEDELQDK (50–400 µM) suppressed lipid accumulation and reduced triglyceride content in palmitic acid (PA)-overloaded HepG2 cells. In conclusion, goat milk–derived bioactive peptides IASAEPTVH, LSTSEENSKK, and TEDELQDK exerted favorable hypolipidemic and hypoglycemic properties.</p>","PeriodicalId":73042,"journal":{"name":"Food frontiers","volume":"7 3","pages":""},"PeriodicalIF":6.9,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://iadns.onlinelibrary.wiley.com/doi/epdf/10.1002/fft2.70208","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
