18:2 Cardiolipin A82842 18:2 Cardiolipin
This specific tetralinoleoyl molecular species is critical for maintaining mitochondrial architecture and bioenergetics in mammalian cells. It tightly binds to and stabilizes the respiratory chain supercomplexes required for efficient oxidative phosphorylation. 18:2 Cardiolipin is also a key player in cellular apoptosis; its peroxidase-driven oxidation is a critical early step that triggers the release of pro-apoptotic factors into the cytosol.
