Lipid Peroxidation

Lipid peroxidation refers to the oxidative degradation of lipids—a biochemical process that occurs when reactive oxygen species (ROS) interact with polyunsaturated fatty acids in plant cell membranes. In cannabis cultivation and storage, lipid peroxidation can affect cannabinoid and terpene stability, particularly in dried flower exposed to light, heat, or oxygen. This process is relevant to genetic expression and phenotypic stability across generations, as oxidative stress influences how cultivars maintain potency and volatile compound profiles. Understanding lipid peroxidation is important for breeders selecting for chemovars with robust lipid antioxidant defenses and for preservation protocols that protect genetic material and finished products from degradation.

Breeders working with oxidative stress tolerance often select parent plants that exhibit natural antioxidant profiles and cellular defense mechanisms. Cultivars with stronger lipid-protective traits may show improved stability across storage cycles and environmental stress, making them valuable parents for developing resilient germplasm.
