Geranylgeranyl pyrophosphate

Geranylgeranyl pyrophosphate (pronunciation: jəˈrænɪldʒəˈrænɪl ˈpaɪroʊˌfɑːsfeɪt) is a molecular compound that plays a crucial role in the biosynthetic processes of various organisms. It is a type of isoprenoid and is involved in the production of certain proteins and enzymes.

Etymology

The term "Geranylgeranyl pyrophosphate" is derived from the names of two isoprene units, "geranyl" and "geranylgeranyl", and "pyrophosphate", a type of phosphate.

Function

Geranylgeranyl pyrophosphate is a key intermediate in the mevalonate pathway and the non-mevalonate pathway, which are responsible for the biosynthesis of terpenes, steroids, and other isoprenoids. It is also involved in the post-translational modification of proteins, a process known as prenylation.
