Oxidative Terpene Conversion

Oxidative terpene conversion describes biochemical processes where terpenes undergo oxidation—losing electrons or gaining oxygen—transforming into secondary metabolites and novel aromatic compounds. This occurs naturally during curing, aging, and storage as cannabis flowers are exposed to light, heat, and atmospheric oxygen. Classic examples include limonene oxidizing to carvone, or myrcene breaking down into smaller volatile molecules. Breeders and cultivators recognize oxidative conversion as a significant factor shaping final aroma profiles, as dried and cured material often expresses markedly different terpene ratios than fresh flower. Understanding these reactions is central to post-harvest management and strain phenotype expression.

Growers and breeders monitor oxidative conversion when designing curing protocols and storage conditions to either preserve or intentionally develop specific aromatic signatures. Lineage records frequently note how certain cultivars' terpene profiles shift predictably during the oxidation window, making this a documented trait in strain development.
