A monoterpene belongs to the class of terpenes, where each terpene hydrocarbon is represented as C5H8. In contrast, a monoterpene is expressed as C10H16 because it consists of two isoprene units in each molecule. Due to this structural difference, monoterpenes are more reactive to heat and exposure to air. As a result, they tend to degrade more rapidly over time.
However, this sensitivity to heat makes monoterpenes highly suitable for activities such as vaping, cooking, and aromatherapy, where their aromatic properties can be fully appreciated. Monoterpenes can be found in various fruits, vegetables, spices, and herbs, including cannabis. Some well-known examples of monoterpenes are limonene, pinene, myrcene, and terpineol.
