Farnesyl pyrophosphate (FPP) is an intermediate in the HMG-CoA reductase pathway used by organisms in the biosynthesis of terpenes and terpenoids. It is the immediate precursor of squalene (via the enzyme squalene synthase), dehydrodolichol diphosphate (a precursor of dolichol), and geranylgeranyl pyrophoshate (GGPP). BiosynthesisFarnesyl pyrophosphate synthase (a prenyl transferase) catalyzes sequential condensation reactions of dimethylallyl pyrophosphate with 2 units of 3-isopentenyl pyrophosphate to form farnesyl pyrophosphate.
RegulationThe above reactions are inhibited by bisphosphonates (used for osteoporosis). Related compounds
