essential fatty acid

Biochemistry
A fatty acid that humans cannot synthesise, which contains double bonds more distal than the COOH end of the 9th carbon atom:
(1) Linoleic acid 18:2 cis-delta 9, delta 12, which has two unsaturated carbon bonds; the first is attached at the methyl end to the 6th carbon (hence, n-6 or omega-6); and
(2) Linolenic acid 18:3 cis-delta 9, delta 12, delta 15.

Fringe nutrition
Some practitioners of alternative healthcare believe cystic fibrosis and ADD/ADHD in children may respond to an increased dietary intake of EFAs.
