Geranyl Pyrophosphate

Geranyl pyrophosphate (GPP) is a crucial biochemical intermediate in cannabis terpene synthesis, functioning as a precursor molecule in the isoprenoid pathway. Rather than a finished aroma compound itself, GPP serves as the building block from which monoterpenes (C10 terpenes) and sesquiterpenes (C15 terpenes) are constructed within the plant's metabolic machinery. Breeders and researchers track GPP accumulation patterns as a marker of terpene production capacity. Understanding GPP's role clarifies how genetic variation controls terpene diversity and abundance in different cultivars.

Breeders working with terpene-rich phenotypes study GPP flux through the isoprenoid pathway to predict and select for high-terpene expression. Strain families showing robust monoterpene profiles typically demonstrate efficient GPP metabolism, making it a useful biochemical benchmark when developing aromatic cultivars.
