| Common Name | 14-Methylhexadecanoic acid |
|---|
| Description | (S)-14-Methylhexadecanoic acid, also known as 14-methylpalmitic acid, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. A methyl-branched fatty acid that is hexadecanoic acid (palmitic acid) substituted by a methyl group at position 14 (S)-14-Methylhexadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, (S)-14-Methylhexadecanoic acid has been detected, but not quantified in, fats and oils and milk (cow). 14-Methylhexadecanoic acid is found in Agelas conifera, Antirrhinum majus, Callyspongia fallax, Erylus formosus, Malvaviscus arboreus, Myrmekioderma rea, Pinus koraiensis, Pinus sibirica, Streptomyces endophyticus and Xestospongia muta. 14-Methylhexadecanoic acid was first documented in 1985 (PMID: 4022192). This could make (S)-14-methylhexadecanoic acid a potential biomarker for the consumption of these foods (PMID: 24548079) (PMID: 15112737) (PMID: 25287814) (PMID: 3663673). |
