coenzyme Q10

A factor present in mitochondria which extracts energy from foods. It has acquired a reputation among fringe nutritionists as being effective in detoxifying patients with an overdose of environmental pollutants; it is also claimed to be beneficial in treating hypertension, obesity, periodontal disease, preventing cancer, increasing longevity and revitalising the immune system.

coenzyme

(ko-en'zim?) [ co- + enzyme]
An enzyme activator; a diffusible, heat-stable substance of low molecular weight that, when combined with an inactive protein called apoenzyme, forms an active compound or a complete enzyme called a holoenzyme (e.g., adenylic acid, riboflavin, and coenzymes I and II).

coenzyme A

A derivative of pantothenic acid, important as a carrier molecule for acetyl groups in many reactions including the Krebs cycle (tricarboxylic acid cycle) and the oxidation of fatty acids.

coenzyme Q

A dietary supplement promoted by alternative medicine practitioners as an antioxidant and as a treatment for gingivitis and heart diseases.

coenzyme Q10

Ubiquinone.

coenzyme Q10

also known as ubiquinone, a non-essential lipid-soluble nutrient found predominantly in animal foods and at low levels in plant foods. In the body it is located primarily in the mitochondria, especially in skeletal and cardiac muscle. As a component of the electron transport chain, it is important for ATP formation. It is also believed to have an antioxidant function, protecting DNA and cell membranes from oxidative damage. For athletes, coenzyme Q10 supplements are claimed to enhance energy production through the electron transport chain, and to reduce the oxidative damage of exercise. Research does not support the claim, reporting either no effect or in some cases an ergolytic rather than ergogenic effect. See also ergogenic aids; appendix 4.4 .

coenzyme Q,

n an enzyme along the electron transport chain. Scientific name: 2,3 dimethoxy-5 methyl-6-decaprenyl benzoquinone; uses: heart disease—including ischemic heart disease, dysrhythmias, congestive heart failure, hypertension, angina pectoris, mitral valve prolapse—diabetes, infertility, Bell's palsy, periodontal disease; precautions: pregnancy, lactation, children; can cause nausea, diarrhea, epigastric pain. Also called
Co-Q10, mitoquinone, ubidecarenone, and
ubiquinone.
