What is Coenzyme Q10?
Coenzyme Q10 is also known as ubiquinone, Coenzyme Q10, CoQ10, trans 2, 3-dimethoxy-5-methyl-6-decaprenyl-1, 4-benzoquinone.
Coenzyme Q is quinone derivative with a variable isoprenoid side chain THe mammalian tissues posses a quinone with 10 isoprenoid units which is known as coenzyme Q 10 (CoQ10).

The molecular formula of the Coenzyme Q10 is C59H90O4
Average Mass of the Coenzyme Q10 is 863.344 Da.
There are three redox states of CoQ10
- fully oxidized (ubiquinone)
- semiquinone (ubisemiquinone)
- fully reduced (ubiquinol)
Coenzyme Q is a lipophilic electron carrier. It can accept electrons from FMNH 2 produced in the ETC by NADH dehydrogenase or FADH 2 produced outside ETC (e.g. succinate
dehydrogenase, acyl CoA dehydrogenase).
Found in all The living tissues
Coenzyme Q is not found in mycobacteria. Vitamin K performs the similar function as coenzyme Q in these organisms. Coenzyme Q has no known vitamin precursor in animals. It is directly synthesized in the body.
Coenzyme is found almost in every cell of the body. It is not vitamin because it is produced by the eukaryotes body. Not need to feed externally.
It presents in the respring eukaryotic cell, mainly in mitochondria. It is a component of the electron transport chain and participates in aerobic cellular respiration, which generates energy in the form of ATP. Ninety-five percent of the human body’s energy is generated this way.

Coenzyme Q10 is used to convert food to energy. It acts as an antioxidant to so, prevents cell from effects of aging.
The cell which having higher energy requirement, have high concentration of Coq10 enzymes, like heart, liver.
Coenzyme Q10 or CoQ10 used as medicine
It is used for medicinal purpose. Antioxidants fight damaging particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death. Scientists believe free radicals contribute to the aging process, as well as a number of health problems, including heart disease and cancer.
Antioxidants, such as CoQ10, can neutralize free radicals and may reduce or even help prevent some of the damage they cause.
Oil based CoQ10 supplements should be taken with meals
