Schematic model for the urinary excretion of L-FABP. In the kidney, fatty acids are transferred into proximal tubules together with albumin. Free fatty acids bind to L-FABP and are relocated to the mitochondria, peroxisome, or nucleus. If lipid peroxidation products accumulate in the proximal tubules, L-FABP binds to those cytotoxic lipids and is excreted into the urine
