👉 Olefine is a chemical compound commonly found in vegetable oils. It is composed of three carbon atoms and one methyl group, making it a saturated hydrocarbon. Olefine is also known as linoleic acid or linolenic acid because its structure resembles those of these two fatty acids. The name "olefine" was coined by the German chemist Friedrich Wilhelm von Schlegel in 1845 to describe this compound.
