coenzyme q10 coq10 sources benefits deficiency & faqs

Coenzyme Q 10 is a naturally occurring fat-soluble antioxidant produced by our body. It is present in most of the living things. CoQ10 is quite similar to vitamins and is also called ‘Ubiquinone ‘as it is present ubiquitously in all cells in all organisms. Coenzyme Q10 is a vital component of the metabolic chemical reactions that generate energy within cells. Our body uses it to produce the energy required for its growth and maintenance.

It comes in two forms: ubiquinol and ubiquinone. Ubiquinol is the anti-oxidant form and ubiquinone is the oxidized form. Our body has the capacity to convert ubiquinone to ubiquinol. It is an essential component of the electron transport system that produces energy in the form of Adenosine Triphosphate (ATP). Ninety-five percent energy requirement of human body gets fulfilled by this process. That’s why the concentration of Q10 is recorded highest in heart, kidney, liver and brain; organs those require maximum energy in our body. Many researches concluded that topical application of CoQ10 has the beneficial effect of preventing premature aging or photoaging.

Q10 Group:

Other than ubiquinone, coenzyme Q10 is also popularly known as ubidecarenone, coenzyme Q, Q10, CoQ10, CoQ. Chemically, it is benzoquinone, where quinone group is abbreviated as Q. It functions in three states —  fully oxidized (ubiquinone), semi-oxidized (ubisemiquinone) and reduced (ubiquinol).


How does CoQ10 Work?

Q10 resembles vitamin and works in three oxidative states. It acts as a two-electron carrier by moving from quinone to quinol & vice versa and single electron carrier from semiquinone to either quinone or quinol. Apart from energy generation, especially ubiquinol effectively works as lipid antioxidant that protects DNA, lipid and protein structures from further modification caused by oxidation. Coenzyme Q10 decreases with the increase of activity and generation of reactive oxygen species (ROS), in diseased condition.
