Enzymatic Degradation

Enzymatic degradation in cannabis refers to the biochemical breakdown of cannabinoids, terpenes, and other plant compounds through enzymatic action—both during plant maturation and post-harvest storage. This process occurs naturally as enzymes like THCA synthase and CBDA synthase convert acidic precursors into their decarboxylated forms, and as oxidative enzymes break down volatile terpenes over time. Environmental factors such as temperature, light exposure, and humidity significantly influence enzymatic activity and the rate of compound degradation. Understanding enzymatic degradation is critical for breeders selecting for stability, shelf-life retention, and chemical profile consistency across generations and storage conditions.

Breeders monitor enzymatic degradation patterns to develop cultivars with robust terpene retention and stable cannabinoid profiles during storage and transport. Selecting parent plants that show slower enzymatic breakdown of target compounds helps create more chemically stable offspring for commercial and research applications.
