Sesquiterpenes are a class of organic compounds made up of three isoprene units, resulting in a molecular structure that typically contains 15 carbon atoms. They are commonly found in essential oils and contribute to the aroma and flavor of various plants, including ginger and coriander. These compounds play significant roles in plant defense and attraction of pollinators. Sesquiterpenes are also studied for their potential medicinal properties, including anti-inflammatory and antimicrobial effects, making them of interest in the fields of pharmacology and natural products research.
