Mitoquinol is a ubiquinone derivative that specifically accumulates in mitochondria due to the covalent attachment of the cation triphenylphosphonium. It functions as an antioxidant, preventing lipid peroxidation-induced apoptosis and protecting mitochondria from oxidative damage.
Mitoquinol是一种泛醌衍生物，由于阳离子三苯基膦的共价连接而在线粒体中特异性积累。它具有抗氧化作用，可以防止脂质过氧化引起的细胞凋亡，并保护线粒体免受氧化损伤。
