I go with Ice Core examples since early sociteties probably didn't have Written Records or maps, and tree rings would only tell if they were fossilized. I hope this helped :)
The enzyme is lipoxygenase.
Lipoxygenase is a variety of enzymes that can cause oxidation of fatty acids. There are several varieties of lipoxygenases, some of which are present in plants. They are involved in the formation of white blood cells that are involved in some severe allergic reactions (anaphylaxis). <em>It is based on this knowledge that antiallergic drugs have been developed to inhibit the activity of lipoxygenase, including reducing inflammatory reactions.</em>
Leukotrien are named thus because they were discovered in leucocytes and that they are unsaturated lipids with 3 conjugated double bonds (trienes) and 20 carbon atoms
