What Is Cetoleic Acid (22:1 n-11)?
Cetoleic acid, known as 22:1 n-11, is a very-long-chain monounsaturated omega-11 fatty acid. It's considered nearly insoluble in water and has a relatively neutral nature.
This unique fatty acid is predominantly found in animal sources.
In the human body, cetoleic acid plays a crucial role in stimulating the synthesis of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) from ALA (alpha-linolenic acid). These long and healthy omega-3 fatty acids are vital for overall well-being. (source ◳)
Moreover, cetoleic acid is believed to offer potential benefits for your skin and can be used as an emollient and softening agent.
