Terpene Synthesis

Terpene synthesis is the biochemical process by which cannabis plants produce volatile aromatic compounds through enzymatic pathways. In cannabis, terpene production begins with the conversion of acetyl-CoA and other precursors into isoprene units, which are then assembled into larger molecular structures like monoterpenes, sesquiterpenes, and diterpenes. This process occurs primarily in specialized glandular trichomes on flowers and leaves, where terpene synthase enzymes catalyze the condensation and cyclization reactions. Environmental factors—including light exposure, temperature, soil nutrient availability, and growth stage—significantly influence both the timing and concentration of terpene synthesis. Understanding terpene synthesis mechanisms helps breeders select for plants with desired aromatic profiles and stability across growing conditions.

Breeders working with terpene profiles study synthesis pathways to stabilize aroma expression across generations and identify genetic markers associated with high terpene production. Knowledge of synthesis regulation helps guide selection for consistent secondary metabolite profiles in cultivar development.
