Linoleic acid

Linoleic acid is an essential omega-6 polyunsaturated fatty acid found in many plant oils, nuts and seeds.

Educational draft · Human scientific and editorial review pending. About review status

It is a structural fatty acid and precursor in the omega-6 family; its dietary context is distinct from that of omega-3 fatty acids.

How it works

The essential omega-6 parent

Humans cannot introduce the first omega-6 double bond, so linoleic acid must come from the diet. It can be elongated and desaturated into other omega-6 fatty acids, including arachidonic acid.

Worth knowing

  • EFSA reference wording. EFSA proposes an adequate intake of 4% of energy for linoleic acid in adults.

A closer look

Omega families are separate

Linoleic acid and ALA are both essential fatty acids but belong to different omega families. Similar naming does not make their pathways interchangeable.

It can supply arachidonic acid

Arachidonic acid can be formed downstream from linoleic acid through elongation and desaturation.
