SS-31 also known as Elamipretide is a mitochondrial targeted tetrapeptide peptide that reduces the production of toxic related oxygen species. It is comprised of 4 amino acids. Dosed at 10 mg for research purposes.
This aromatic–cationic tetrapeptide associates with inner-mitochondrial-membrane lipids (notably cardiolipin). Consequently, researchers employ it to explore electron-transport organisation, bioenergetics, and redox pathways in model systems.
