Ubiquinone is a quinone found in the lipid bilayer and involved in the respiratory electron transport chain as an electron carrier[1]. As an electron carrier ubiquinone donates or picks up electrons in redox reactions. Ubiquinone is a small hydrophobic molecule ubiquinone has the ability to move easily through the lipid bilayer and is not located in a fixed position.
Ubiquinone, also known as coenzyme Q, plays an important role in the electron transport chain in mitochondria[2]. Coenzyme Q transfers electrons from complex I and complex II to complex III in the electron transport chain and is synthesised in all eukaryotic cells. Due to the fact that ubiquinone is essential in the production of ATP, a deficiency in the cofactor can result in multiple diseases[3].
