SS-31

SS-31 is a mitochondria-targeted tetrapeptide studied for its potential to support mitochondrial structure and function. This peptide is designed to selectively bind to cardiolipin, a phospholipid found within the inner mitochondrial membrane, where it may help stabilize mitochondrial integrity and optimize cellular energy processes. Because mitochondria play a central role in ATP production, cellular health, and metabolic efficiency, SS-31 has become a major focus in research on aging biology and mitochondrial dysfunction. Scientific studies have examined SS-31 for its potential to enhance oxidative phosphorylation, improve mitochondrial biogenesis, and restore normal mitochondrial dynamics in models of cellular stress or age-related decline. Research has also investigated its ability to reduce oxidative damage, limit inflammatory signaling, and support cell-survival pathways. These mechanistic findings have positioned SS-31 as a promising molecule in studies related to skeletal muscle performance, mitochondrial resilience, and metabolic vitality. SS-31 remains a significant peptide in mitochondrial and longevity research due to its targeted mechanism and its potential to support cellular energy systems and resilience under stress.
