Chemical Information

FooDB Name

N-Eicosane

Description

Eicosane, also called icosane, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CH3-[CH2]18-CH3, and consist entirely of hydrogen atoms and saturated carbon atoms. Eeicosane is a hydrocarbon lipid molecule that is very hydrophobic, practically insoluble in water, and relatively neutral. Eicosane has an alkane, and a colorless and waxy taste. It is found in highest concentrations in lemon balms. Eicosane has also been detected in allspices, papaya, coconuts, lindens, and hyssops. This could make eicosane a potential biomarker for the consumption of these foods. Eicosane was associated with Parkinson's disease (PMID: 31041379).
