Rumenic acid,also known asbovinic acid,is aconjugated linoleic acid(CLA) found in the fat ofruminantsand indairy products.It is anOmega -7trans fatty acid.Its lipid shorthand name is cis-9, trans-11 18:2 acid. The name was proposed by Krameret al.in 1998.[1]It can be considered as the principal dietary form, accounting for as much as 85-90% of the totalCLAcontent in dairy products.[2]
Biosynthesis and biotransformations[edit]
Rumenic acid is produced fromvaccenic acidby the action of unsaturase enzymes.[3]Rumenic acid is converted back to vaccenic acid en route tostearic acid
