Summary of cellular FFA functions

FunctionMechanism
Cell membrane structural integrityLipid bilayer synthesis (PL and cholesterol synthesis)
Lipid rafts and caveolae
Energy (ATP) productionMitochondrial FA β oxidation
Posttranslational protein modificationPrenylation (lipidation)
Intracellular signaling and transcriptional regulationFA pathway intermediates or FA ligation of nuclear receptors
