Plant lipases and lipoxygenases are the main enzymes responsible for change of FA because plant lipases release FA from damaged tissues after cutting and followed ensiling (CHOW et al., 2004) and plant lipoxygenases oxidize FA (FEUSSNER & WASTERNACK, 2002).
It happens through the changes in substrates availability and the effect on the activity of basic enzymes: cyclooxygenases and lipoxygenases [5].
Several enzymes are involved in this regulation of inflammation, cyclooxygenases 1 and 2 [1], lipoxygenases [1], cytochrome P 450 (CYP) epoxygenases and [alpha]-hydroxylases [2], and also the nonenzymatic processes of AA metabolism like the free radicalcatalyzed peroxidation [3].

JAs originate from a-linolenic acid released from the lipid pool of plant cells by lipases and are subsequently oxygenated by lipoxygenases (LOXs) to form hydroperoxide derivatives (cyclopentanones) [3-5].

Among lipoxygenases, 12/15-LOX seems to play a particular role in the brain and it is also called a "neuronal isoform" [2].
At the cellular level, multiple mechanisms including lipoxygenases are involved in differentiation of preadipocytes into adipocytes and in their intracellular lipid accumulation [33].
