Lipid Peroxidation Resistance Separates Long-Lived Species from Rapidly Aging Mammals

Mechanism: Long-lived species resist lipid peroxidation damage by maintaining higher membrane saturation and improved antioxidant allocation. Readout: Readout: This leads to robust membrane integrity and extended lifespans compared to rapidly aging mammals.

Membrane lipid composition dictates oxidative damage susceptibility. Long-lived species accumulate less peroxidation damage despite higher metabolic spans. The difference is likely elevated membrane saturation and antioxidant allocation to membranes that mammals lose with age.
