What Is Cetoleic Acid?

Cetoleic acid, 22:1 n-11, is a very-long-chain monounsaturated omega-11 fatty acid. It’s considered to be practically insoluble, in water, and relatively neutral.

It’s mostly found in our biofluids. In the body, cetoleic acid stimulates the synthesis of EPA and DHA from ALA.
