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-7trans fatty acid. Its lipid shorthand name is cis-9, trans-11 18:2 acid. The name was proposed by Kramer et al. in 1998.[1] It can be considered as the principal dietary form, accounting for as much as 85-90% of the total CLA content in dairy products.[2]
Biosynthesis and biotransformations
Rumenic acid is produced from vaccenic acid by the action of unsaturase enzymes.[3] Rumenic acid is converted back to vaccenic acid en route to stearic acid
