[Mechanisms for tissue transport of fatty acids].

Fatty acids (FA) play an important role in energy metabolism. They are not only used as substrates for energy production but are also involved in many other metabolic pathways. However, the exact mechanisms by which FA are taken up by the cells are not yet fully understood. Fatty acids circulating in blood cross the cell membranes partly via a mechanism facilitated by plasma membrane proteins and partly via a passive diffusion mechanism, the former mechanism being of major importance.
