Vaccenic acid is a trans fat found in the fat of ruminants and in dairy products. Its IUPAC name is trans-7-octadecenoic acid, and its lipid shorthand name is 18:1 trans-11. The name was derived from the Latin vacca (cow).[1]
Vaccenic acid was discovered in 1928 in animal fats and butter. It is the main trans fatty acid isomer present in milk fat.[1] Mammals convert it into rumenic acid, a conjugated linoleic acid,[1][1] where it shows anticarcinogenic properties.[1]
Its stereoisomer, Cis-Vaccenic acid is an Omega-7 fatty acid found in Sea Buckthorn (Hippophae rhamnoides) oil. [1] Its IUPAC name is cis-7-octadecenoic acid, and its lipid shorthand name is 18:1 cis-11.
Old Person Smell
In the April 2001 issue of THE JOURNAL OF INVESTIGATIVE DERMATOLOGY, Shinichiro Haze et al published an article entitled: "2-Nonenal, Newly Found in Human Body Odor Tends to Increase with Aging". [1]
In this article it was suggested that omega-7 unsaturated fatty acids, such as palmitoleic acid and vaccenic acid, found on the skin surface may be the cause of the phenomenon commonly known as "old person smell".
