In ways that are poorly understood and require further study, EFAs seem to be involved in electron and energy transport. EFAs are involved in the transport (esterification) of cholesterol. ALA and its derivatives can lower elevated blood fats (serum triglycerides)
Much is still unknown about the functions of EFAs in our body. Of the two, LA has been studied far more extensively than ALA. Both are difficult to work with, because they are easily destroyed, but ALA is five times
The usefulness of LA and ALA in our body results from their chemical properties.
EFAs attract oxygen. This property made EFA-rich oils useful to the paint industry as ‘drying’ oils, which dry and harden when exposed to air. Oils commonly
