Enzymatic Activity

Enzymatic activity in cannabis refers to the metabolic processes that break down and transform organic compounds during plant growth, curing, and storage. These biochemical reactions—catalyzed by endogenous enzymes—alter cannabinoid precursors, degrade chlorophyll, and generate secondary metabolites responsible for aroma and flavor development. Enzymatic processes are particularly active during the post-harvest curing phase, where controlled moisture and temperature allow enzymes like polyphenol oxidase and lipoxygenase to operate. Cannabis cultivars vary in baseline enzyme expression and activity rates, influencing how quickly aromatic compounds mature. Understanding enzymatic activity is central to breeding for specific flavor profiles and post-harvest management strategies.

Breeders working with enzymatic expression select for cultivars that develop desired aromatic complexity during curing windows. Lineage records frequently report that certain parent plants demonstrate more robust enzymatic conversion of precursor compounds, making them valuable crossing stock for flavor-forward breeding programs.
