Rumenic acid is an conjugated linoleic acid 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.[1] It is formed along with vaccenic acid by biohydrogenation of dietary polyunsaturated fatty acids in the rumen.[2]
Biological properties
Laboratory studies indicate that rumenic acid shows anticarcinogenic properties.[3]
