Natural Product Identification
Common NameNonadecanoic acid
DescriptionNonadecanoic acid, also known as n-nonadecanoic acid or nonadecylic acid or C19:0, 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, with nonadecanoic acid (its ester is called nonadecanoate) having 19 carbon atoms. Nonadecanoic acid is a very hydrophobic molecule, practically insoluble (in water). It is a solid with a melting point of 69.4°C. It can be found in bacteria, plants, and animals (including animal milk) (Nature 176:882; PMID: 14168161 ). It is secreted by termites (Rhinotermes marginalis) as part of its defence mechanism (Comp. Biochem. Physiol. B 71:731).
