EPA is eicosapentaenoic acid.
eicosa is greek for twenty; penta greek for five; en(e) means double bond, or unsaturated; -oic acid means carboxylic acid.
EPA is actually all-cis-delta-5,8,11,14,17-eicosapentaenoic acid.
DHA is the 22-carbon, six-unsaturated, carboxylic acid all-cis-delta-4,7,10,13,16,19-docosahexaenoic acid.
The term EFA (Essential Fatty Acid) has no fixed meaning, but it tends to be a reference to the alpha and gamma isomers of linolenic acid. This term is being redefined through alternative meanings at the present time.
EFAs are all PUFAs (polyunsaturated fatty acids), but not all PUFAs are EFAs.
