(biochemistry) A certain benzoquinol, the reduced product of ubiquinone, also called coenzyme Q10.
Examples
For example, in E. coli, there are two different types of ubiquinol oxidase using oxygen as an electron acceptor.
This QH 2 is then released from the enzyme. citation As coenzyme Q is reduced to ubiquinol on the inner side of the membrane and oxidized to ubiquinone on the other, a net transfer of protons across the membrane occurs, adding to the proton gradient.
Importantly, if you’re on a statin drug, you need at least 100 mg to 200 mg of ubiquinol or CoQ10 per day, or more.
Reduction of ubiquinone also contributes to the generation of a proton gradient, as two protons are taken up from the matrix as it is reduced to ubiquinol (QH 2 ).
When Q accepts two electrons and two protons, it becomes reduced to the ubiquinol form (QH 2 ); when QH 2 releases two electrons and two protons, it becomes oxidized back to the ubiquinone (Q) form.
They’re actually the same molecule, but when CoQ10 is reduced it takes on two electrons, which turns it into ubiquinol.
