Enzymatic Conversion Pathways

Enzymatic conversion pathways describe the biochemical processes through which cannabis plants synthesize terpenes from precursor molecules. These pathways involve specific enzymes that catalyze sequential reactions, converting simple carbon compounds (like geranyl pyrophosphate) into the diverse terpene library found across cultivars. Breeders and geneticists study these pathways to understand how genetic variation influences terpene expression and ratios. Different cultivar lineages often exhibit distinct enzymatic efficiencies, affecting which terpenes accumulate during flowering. Understanding these mechanisms helps plant scientists contextualize why related genetics produce different aromatic profiles despite shared ancestry.

Breeders working toward specific terpene compositions study enzymatic pathway efficiency as a heritable trait. Selecting for or against certain enzyme expression patterns can shift the ratio of monoterpenes to sesquiterpenes, or favor accumulation of particular compounds like limonene or β-caryophyllene within a genetic line.
