SS-31 is a mitochondria-targeted synthetic peptide from the Szeto-Schiller (SS) family, designed to protect and restore mitochondrial function. It selectively accumulates in the inner mitochondrial membrane (IMM), stabilizes cardiolipin, reduces oxidative stress, and enhances ATP production. SS-31 has been widely studied for its therapeutic potential in neurodegenerative, cardiovascular, metabolic, and renal conditions where mitochondrial dysfunction is a core issue.
