Merck, C9538-1G, Coenzyme Q₁₀

Coenzyme Q (CoQ), also known as ubiquinone, is a lipid-soluble antioxidant and is an essential component of the mitochondrial electron transport chain. The molecule contains a biologically active quinone with a benzoquinone ring and an isoprenoid sidechain. Q10 is synthesized in the cytoplasm and mitochondria () which generates ATP through aerobic cellular respiration. CoQ10 is required for the optimal functioning of the immune system and for cardiovascular health (). The ability to repress inflammatory gene expression exhibits its anti-inflammatory property ( ) Genetic failure or ageing results in CoQ10 deficiency, indicated by suppression of immune function. ()
