Ketone Terpenes

Ketone terpenes represent a distinct chemical class within cannabis volatile compounds, characterized by a carbonyl (C=O) functional group in their molecular structure. This chemical feature differentiates them from the more abundant hydrocarbon terpenes like limonene and pinene. Notable members of this family include acetone, damascenone, and humulenone, though they typically appear in trace quantities in cannabis chemotypes. Ketones are commonly associated with woody, earthy, and sometimes fruity aromatic notes in strain profiles. Their presence is often linked to oxidation processes during curing and storage, making them significant markers in post-harvest cannabis chemistry.

Breeders working with ketone-producing phenotypes often monitor these compounds as secondary aroma markers, as they can emerge during the maturation and drying phases rather than existing prominently in fresh plant material. Understanding ketone terpene expression helps cultivators predict how aroma profiles may develop and shift during the cure, informing strain selection for desired sensory outc
