Oxidation Pathways

Oxidation pathways refer to the biochemical processes through which cannabis plants convert primary terpenes into secondary and tertiary compounds over time. These transformations occur during growth, drying, curing, and storage, often producing new aromatic and chemical profiles from the original plant material. Key pathways involve enzymatic degradation and air exposure, particularly affecting monoterpenes like limonene and pinene as they convert to compounds like carvone or other oxidized derivatives. Understanding oxidation is critical for seed collectors and breeders because it directly impacts how a strain's aroma and chemical profile evolve post-harvest. Documentation of oxidation behavior helps breeders predict stability and consistency across cultivation cycles and storage conditions.

Breeders monitor oxidation rates when selecting for stable chemotype expression and shelf-life predictability. Strains with slower or more desirable oxidation patterns are often preferred for seed preservation programs, as they maintain consistent terpene signatures across generations.
