Rumenic acid, also known as bovinic acid, is a conjugated linoleic acid (CLA) found in the fat of ruminants and in dairy products. It is a omega-7 trans fat. Its lipid shorthand name is cis-9, trans-11 18:2 acid.The name was proposed by Kramer "et al" in 1998.cite journal |author=Kramer J, Parodi P, Jensen R, Mossoba M, Yurawecz M, Adlof R |title=Rumenic acid: a proposed common name for the major conjugated linoleic acid isomer found in natural products |journal=Lipids |volume=33 |issue=8 |pages=835 |year=1998 |pmid=9727617 |doi=10.1007/s11745-998-0279-6] It is formed along with vaccenic acid by biohydrogenation of dietary polyunsaturated fatty acids in the rumen.cite journal
