| Popis: | When postheparin plasma was incubated with a coconut oil substrate, a decrease in optical density and an increase in unesterified fatty acids occurred. The increase in unesterified acids was prevented by previous intravenous injection of Triton to rats. Addition of post-Triton plasma to a system containing postheparin plasma and coconut oil emulsion inhibited the lipoprotein lipase activity. Incubation of Triton with coconut oil substrate before addition of postheparin plasma caused inhibition of lipoprotein lipase activity. It is concluded that inhibition of lipoprotein lipase activity by Triton is due to modification of the substrate such that the enzyme can no longer act. Further, it is suggested that the chief cause of Triton hyperlipemia is coating of the plasma lipoproteins by Triton resulting in their faulty catabolism. |
