Why is ubiquinone aka CoQ called that? Draw its structure and then draw its reduced structure. (CoQ and CoQH₂ or UQ and UQH₂) What kind of tail does it have attached to the quinone portion of the molecule?

Expert Solution

CoQ is coenzyme Q. it is the third complex of respiratory chain. it accepts an electron from both complex form. gets reduced and then gets oxidised as it passes.

Coenzyme Q_10, also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQ, or Q₁₀ is a coenzyme that is ubiquitous in animals and most bacteria and hence the name is ubiquinone. It is a 1,4-benzoquinone, where Q refers to the quinone chemical group and 10 refers to the number of isoprenyl chemical subunits in its tail. here the oxidised and reduced forms,

The oxidized structure of CoQ₁₀ is shown on the top-left. The various kinds of Coenzyme Q may be distinguished by the number of isoprenoid subunits in their side-chains. The most common Coenzyme Q in human mitochondria is CoQ₁₀. Q refers to the quinone head and 10 refers to the number of isoprene repeats in the tail.
