Conjugated linoleic acid (CLA) inhibits fatty acid synthetase activity in vitro.
This paper describes the in vitro effect of conjugated linoleic acid (CLA) on fatty acid biosynthesis. Among the rat liver enzymes involved in fatty acid biosynthesis, fatty acid synthetase (FAS) showed the largest activity fluctuation with the types of fatty acids. Of the fatty acids, CLA was the most potent inhibitor of FAS, and the 9c, 11t-rather than the 10t, 12c-isomer showed greater inhibition. CLA also significantly lowered the incorporation of [14C]-acetate into phospholipid in breast cancer cells, supporting the view that CLA inhibits fatty acid biosynthesis through the interaction with FAS.
