Cannabis Compound Identification
Common NamePentacosane
Descriptionn-Pentacosane, also known as CH3-[CH2]23-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and consist entirely of hydrogen atoms and saturated carbon atoms. n-pentacosane is a hydrocarbon lipid molecule that is very hydrophobic, practically insoluble in water, and relatively neutral. n-Pentacosane has been detected in coconuts, avocado, ginkgo nuts, cardamoms, and lindens. This could make n-pentacosane a potential biomarker for the consumption of these foods. Pentacosane is also present in the essential oil of cannbis obtained by extraction and steam distillation (PMID: 6991645 ). n-Pentacosane is also found in cannabis smoke and is volatilized during the combustion of cannabis ( Ref:DOI ).
