Aliphatic Lubricant Oils
Olefins exist profusely in plant organisms and animals as large ratios of them form fish, vegetable oils (they control the buildup of fatty substances in the arteries), vitamin A, and other chromosomes as in orange, carrots and tomato are olefins. Olefins are also produced at the time of fruit and vegetable ripening and fermentation (ethylene).
Olefins are sweet and bitter. They contain one duplication between carbon atoms at least. The double chain and the structuring nature of associated carbonyl chain make hydroolefins bitter and Cork unstable. In the absence of hydrogen or other elements, they will have high reactive ability so they are bitter. To react with them, olefins will react with each other to form high molecular weight polymers.
