![Isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) are condensed by geranyl pyrophosphate synthase (dimethylallyltranstransferase) to produce geranyl pyrophosphate (GPP) and pyrophosphate. The carbon skeletons of DMAPP and IPP have been colored to indicate their location in GPP.](/Images/godic/202501/15/Synthesis_of_geranyl_pyrophosphate2348.png")
Geranyl pyrophosphate (GPP), also known as geranyl diphosphate (GDP), is an intermediate in the HMG-CoA reductase pathway used by organisms in the biosynthesis of farnesyl pyrophosphate, geranylgeranyl pyrophosphate, cholesterol, terpenes and terpenoids
