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 an omega-7 trans fatty acid. Its lipid shorthand name is cis-9, trans-11 18:2 acid. The name was proposed by Kramer et al. in 1998.{{cite journal |vauthors=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 |page=835 |year=1998 |pmid=9727617 |doi=10.1007/s11745-998-0279-6|s2cid=10693714 }} It can be considered as the principal dietary form, accounting for as much as 85-90% of the total CLA content in dairy products.{{cite web

Biosynthesis and biotransformations
Rumenic acid is produced from vaccenic acid by the action of unsaturase enzymes.{{cite journal |doi=10.1093/ajcn/76.3.504|title=Bioconversion of vaccenic acid to conjugated linoleic acid in humans |year=2002 |last1=Turpeinen |first1=Anu M. |last2=Mutanen |first2=Marja |last3=Aro |first3=Antti |last4=Salminen |first4=Irma |last5=Basu |first5=Samar |last6=Palmquist |first6=Donald L. |last7=Griinari |first7=J Mikko |journal=The American Journal of Clinical Nutrition |volume=76 |issue=3 |pages=504–510 |pmid=12197992 |doi-access=free }} Rumenic acid is converted back to vaccenic acid en route to stearic acid
