Common Name | Vaccenic acid |

Description | Vaccenic acid is a naturally occurring trans fatty acid. It is the predominant kind of trans-fatty acid found in human milk, in the fat of ruminants, and in dairy products such as milk, butter, and yogurt. Trans fat in human milk may depend on trans fat content in food. Its IUPAC name is (11E)-11-octadecenoic acid, and its lipid shorthand name is 18:1 Trans-11. The name was derived from the Latin vacca (cow). Vaccenic 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. Vaccenic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. |
