Lipoxygenase Pathway Volatiles

Lipoxygenase pathway volatiles are organic compounds generated when plant cell membranes are disrupted, triggering enzymatic oxidation of polyunsaturated fatty acids. This biochemical cascade produces compounds commonly associated with fresh, green, herbaceous, and grassy aromatics—often detected as 'cut grass' or leafy notes in raw cannabis tissue. The pathway generates volatile aldehydes and alcohols including hexanal, hexenol, and 3-hexenal, which form part of a strain's headspace profile before and after harvest. Breeders and cultivators increasingly recognize this family as a marker of fresh-plant terroir and post-harvest handling conditions, making it relevant to breeding programs focused on aroma preservation and sensory complexity.

Breeders working in preservation-focused programs monitor lipoxygenase volatiles as indicators of plant stress response and tissue integrity during growth. The presence and intensity of these compounds can influence decisions about harvest timing, drying protocols, and cultivar selection for specific aromatic goals.
