Substance Name: Conjugated linoleic acid
RN: 121250-47-3


  • MeSH: A collective term for a group of around nine geometric and positional isomers of LINOLEIC ACID in which the trans/cis double bonds are conjugated, where double bonds alternate with single bonds.

    PubMed: Conjugated linoleic acid (CLA) is a naturally occurring fatty acid that is produced by a bio-hydrogenation process in the rumen, and thus is present in dairy products and ruminant meat. In this case the predominant isomer formed is 9cis,11trans. However, CLA includes 28 positional and geometrical isomers, of which only 9cis,11trans and 10trans,12cis have thus far been proven to possess biological activities.
