Muscle fatty acid uptake during exercise: possible mechanisms.
Muscle long-chain fatty acid (LCFA) utilization may be regulated by the ability of the muscle cell to carry LCFA across the plasma membrane. The presence of saturable LCFA uptake kinetics and the identification of putative LCFA transporter proteins whose expression can be modulated by acute and chronic exercise adaptations provide evidence for the existence of a carrier-mediated transport system in muscle.
