Abstract:Dietary n-3 long chain polyunsaturated fatty acids (LCPUFA) are hypothesized to be natural doping agents in migratory shorebirds, enabling prolonged flight by increasing membrane fluidity and oxidative capacity of the flight muscles. Animals can obtain n-3 LCPUFA from the diet or by conversion of dietary α-linolenic acid, 18:3 n-3. However, capacity to meet n-3 LCPUFA requirements from 18:3 n-3 varies among species. Direct tests of muscle oxidative enhancement and fatty acid conversion capacity are lacking in … Show more
