Abstract:The digestion and absorption properties of 1,3-dipalmitoyl-2-oleoyl glycerol (POP)-rich lipids was evaluated using in vitro gastrointestinal digestion and a Caco-2 cell-mediated coupled model. Caco-2 cell viability and monolayer integrity were assessed by an MTT assay and transepithelial electrical resistance. The IC50 for bile salts, pancreatin, and free fatty acid (FFA) were 0.22 mM, 0.22 mg/mL, and 1.47 mM, respectively, and no cytotoxicity was observed for bovine serum albumin (0.01–0.20 mM) or triacylglyc… Show more
