Coenzyme Q10 – The "ubiquitous" natural substance
Coenzyme Q10, also known as ubiquinone 10, is an important representative of the ubiquinones. This class of compounds includes methylated benzoquinone derivatives with an isoprenoid side chain and is structurally related to other lipophilic natural substances such as vitamins K and E. The name "ubiquitous" derives from the Latin word "ubique," meaning "everywhere," as ubiquinones are widespread in nature.
Functions of Coenzyme Q10
The high concentration of coenzyme Q10 in tissues with a high metabolic rate and mitochondrial density, such as the heart and liver, highlights its central role in cellular energy metabolism. The main functions of coenzyme Q10 include:
- Energy production: Coenzyme Q10 plays a key role in the respiratory chain by transferring electrons from NADH + H+ to oxygen. This leads to the formation of ATP, the universal biological energy currency of the organism.
- Redox system: Coenzyme Q10 exists in two forms – the oxidized form ubiquinone (Q10ox) and the reduced form ubiquinol (Q10red). Its ability to toggle between these states is essential for its function as an antioxidant and in energy production.
- Collaboration with other nutrients: Coenzyme Q10 works closely with vitamins B2 (riboflavin) and niacin as well as the minerals iron and magnesium to support the cell's normal energy metabolism.
Recommended dosage and sources
Coenzyme Q10 is found in various foods, with animal products having higher concentrations. Good sources of coenzyme Q10 include:
- Organ meats (especially heart and liver)
- Muscle meat
- Fish
- Whole grain products and some plant sources (in smaller amounts)
For targeted intake, supplementation with dietary supplements can also be considered.
Good to know!
With increasing age, the level of coenzyme Q10 in the blood and tissues decreases. The human body can synthesize coenzyme Q10 from the amino acid L-tyrosine. Important cofactors for this synthesis are pantothenic acid (as coenzyme A), riboflavin (B2), niacin (B3), folate, and vitamin B12. The key enzyme in this process is HMG-CoA reductase, which also plays a central role in endogenous cholesterol synthesis.
Conclusion
Coenzyme Q10 is an essential natural substance that plays a central role in energy metabolism and acts as an antioxidant. It supports energy production in cells and works closely with other vitamins and minerals. An adequate intake through diet or supplements can help take advantage of the health benefits of coenzyme Q10.
