Free Fatty Acid Receptors

Free fatty acids (FFAs) were for long believed to influence cellular metabolism. Hoever, the discovery that FFAs actually mediate their effects through one of three G-protein coupled receptors (GPCRs) – Free Fatty Acid Receptors 1-3 (FFAR1-3), has initiated a number of studies in order to assess their implication in health and disease.
Like all other GPCRs, FFAR1-3 have seven transmembrane domains, an extracellular N-terminal tail and an intracellular C-terminus.
