Metabolite Identification
Common NameMelissic acid
DescriptionMelissic acid, also known as melissate, is a member of the class of compounds known as very long-chain fatty acids. Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Thus, melissic acid is considered to be a fatty acid lipid molecule. Melissic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Melissic acid can be found in dandelion and orange mint, which makes melissic acid a potential biomarker for the consumption of these food products. Melissic acid (or triacontanoic acid) is a saturated fatty acid .
