All of the Following are Terpenes EXCEPT

Question

All of the following are terpenes EXCEPT:
A) squalene.
B) α-tocopherol (vitamin E).
C) coenzyme Q (UQ).
D) limonene.
E) cetyl palmitate (spermaceti).

Accepted Answer

Cetyl palmitate (spermaceti) is not a terpene; it is an ester derived from palmitic acid and cetyl alcohol. Terpenes are a large and diverse class of organic compounds, produced by a variety of plants, especially conifers, and by some insects. They are made from isoprene units, and squalene, α-tocopherol (vitamin E), coenzyme Q (UQ), and limonene are all examples of compounds built from isoprene units, thus classifying them as terpenes or terpenoids.
