Farnesyl pyrophosphate (FPP), also known as farnesyl diphosphate (FDP), is an intermediate in the biosynthesis of terpenes and terpenoids such as sterols and carotenoids.[1] It is also used in the synthesis of CoQ (part of the electron transport chain), as well as dehydrodolichol diphosphate (a precursor of dolichol, which transports proteins to the ER lumen for N-glycosylation).

Biosynthesis

Farnesyl pyrophosphate synthase (a prenyl transferase)[2] catalyzes sequential condensation reactions of dimethylallyl pyrophosphate with 2 units of 3-isopentenyl pyrophosphate to form farnesyl pyrophosphate, as is shown in the following two steps:

  • Geranyl pyrophosphate then reacts with another molecule of 3-isopentenyl pyrophosphate to form farnesyl pyrophosphate

Pharmacology

The above reactions are inhibited by bisphosphonates (used for osteoporosis).[3] Farnesyl pyrophosphate is a selective agonist of TRPV3.[4]
