CoQ10 functions as an essential electron carrier in the mitochondrial electron transport chain (Complex I to III and Complex II to III), directly supporting oxidative phosphorylation and ATP synthesis. In its reduced form (ubiquinol), it serves as a potent lipid-soluble antioxidant, protecting mitochondrial membranes and LDL particles from peroxidation. It also modulates the mitochondrial permeability transition pore (mPTP) and supports endothelial NO synthase coupling.
