DMAPP, also known as Dimethylallyl pyrophosphate, is an isoprenoid precursor found in all life forms. It serves as an isomer of isopentenyl pyrophosphate (IPP).
Geranyl pyrophosphate is an intermediate in the mevalonate pathway. It is formed from dimethylallyl pyrophosphate and isopentenyl pyrophosphate by geranyl pyrophosphate synthase. Geranyl pyrophosphate is used in the biosynthesis of farnesyl pyrophosphate , geranylgeranyl pyrophosphate , cholesterol, terpenes, and terpenoids.
