| description | <p>Abstract</p> <p>Background</p> <p>Dietary 1(3)-behenoyl-2,3(1)-dioleoyl-<it>rac</it>-glycerol (BOO) has been reported to inhibit pancreatic lipase activity <it>in vitro </it>and suppress postprandial hypertriacylglycerolemia in humans. In the present study, the anti-obesity activities of BOO and its inhibitory effects on lymphatic triacylglycerol (TAG) absorption were investigated in rats.</p> <p>Methods</p> <p>In Experiment 1, rats were fed either BOO or soybean oil (SO) diet for 6 weeks. In the BOO diet, 20% of SO was replaced with an experimental oil rich in BOO. In Experiments 2 and 3, rats cannulated in the thoracic duct were administered an emulsions containing trioleoylglycerol (OOO) or an oil mixture (OOO:BOO, 9:1). Tri[1-<sup>14</sup>C]oleoylglycerol (<sup>14</sup>C-OOO) was added to the emulsions administered in Experiment 3.</p> <p>Results</p> <p>No observable differences were detected in food intake or body weight gain between the BOO and SO groups in Experiment 1. Plasma and liver TAG concentrations and visceral fat weights were significantly lower in the BOO group than in the SO group. The apparent absorption rate of fat was significantly lower in the BOO group than in the SO group. In Experiment 2, the lymphatic recovery of oleic and behenic acids was significantly lower at 5 and 6 h after BOO administration than after OOO administration. In Experiment 3, the lymphatic recovery of <sup>14</sup>C-OOO was significantly lower at 5 and 6 h after BOO administration than after OOO administration.</p> <p>Conclusions</p> <p>These results suggest that BOO prevents deposition of visceral fat and hepatic TAG by lowering and delaying intestinal absorption of TAG.</p> |
