Why it matters

What it does in your body

  • Minor energy-providing fat found alongside oleic acid in many foods
  • A structural component of some plant oils, notably jojoba and canola
  • Present in trace amounts in cell membranes and tissues

Intake guidance

How much you need

There is no separate daily target for eicosenoic acid. It is a minor part of your total dietary fat, and the body can make monounsaturated fatty acids, including by elongating oleic acid, so it is not considered essential.

What affects it

What affects your intake

Food source

It is most concentrated in jojoba oil, but for eating it appears mainly in macadamia nuts, canola oil, and some marine fish.

Small quantities

In typical diets it occurs only in small amounts, usually alongside larger amounts of oleic acid.

In practice

Good to know

Good to know: eicosenoic acid, also called gondoic acid, is a minor monounsaturated fat you get in small amounts from nuts, canola oil, and fish. It is chemically related to oleic acid and behaves as a typical monounsaturated fat in the diet. It is best known from jojoba oil, which is used in cosmetics rather than eaten. It has no special dietary requirement or notable concern at ordinary intakes.

Where to get it
