Dietary and nutritional aspects of fatty acid binding proteins

Information on cytosolic fatty acid binding proteins (FABP) related to dietary and pharmacological manipulations is discussed in terms of FABP function. FABP present in liver, heart, intestinal mucosa and omental fat responds to different diets. A parallel change occurs in tissue levels of FABP and metabolism of fatty acids. It seems FABP might play a role in lipid metabolism by interacting with membrane bound enzymes. The available data also support the argument in favor of FABP involvement in intracellular transport, compartmentalization and channeling of fatty acids.
