Vaccenic acid Vaccenic acid, also known as ("E")-octadec-11-enoic acid is a naturally occurring trans-fatty acid found in the fat of ruminants and in dairy products such as milk, butter, and yogurt. It is also the predominant fatty acid comprising trans fat in human milk. Its IUPAC name is ("E")-11-octadecenoic acid, and its lipid shorthand name is 18:1 "trans"-11. The name was derived from the Latin "vacca" (cow).
