    Academic text (2000)

  • The low level of eicosapentaenoic acid in the fish may also help to explain the high levels of arachidonic acid in the fish-eating group, since eicosapentaenoic acid competes with arachidonic acid more efficiently than docosapentaenoic acid for esterification into lipids.

arachidonic positive

Morphology

arachidonic = arachidon + ic

The form 'arachidon-' is a specialized combining form (from the genus Arachis / chemical names) not a productive standalone English base, so the adjective's meaning is technical and not transparently derivable by an average learner.

Etymology

Arachidonic comes from the plant name Arachis, the peanut, because a related fatty acid was first found in peanut oil. So, arachidonic means 'relating to arachidonic acid', a kind of fat in body cells that helps cause inflammation.
