Enzymatic Degradation

Enzymatic degradation refers to the biochemical breakdown of cannabis plant compounds—including cannabinoids, terpenes, and plant proteins—through the action of naturally occurring enzymes. This process occurs continuously during plant growth, post-harvest curing, storage, and aging. Breeders and cultivators monitor enzymatic activity because it affects final cannabinoid profiles, terpene ratios, and overall chemical stability of dried material. Temperature, humidity, light exposure, and time all influence enzymatic degradation rates. Understanding this mechanism is essential for preservation strategies and predicting how a strain's chemical composition will shift over weeks or months.

Breeders and geneticists study enzymatic degradation patterns to develop cultivars with stable cannabinoid retention during curing and storage. Strains bred for slower enzymatic breakdown of THCA or CBDA may maintain potency longer post-harvest, while some breeders intentionally select for rapid decarboxylation under specific conditions.
