SS-31
Mitochondria-targeting tetrapeptide studied for cardiolipin binding, energy, and oxidative-stress research.
SS-31 — also known as Elamipretide — is the headline compound in mitochondrial research: the tool labs reach for when the question is cellular energy and aging at the level of the cell's powerhouse. It is a small four-amino-acid peptide that homes in on cardiolipin, a lipid found only in the inner mitochondrial membrane, and is studied around mitochondrial function, energy production, and oxidative stress.
Its specific affinity for the mitochondrial membrane is what sets it apart from general antioxidant research tools.
