Chemical Information
FooDB NameN-Pentacosane
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.
