What is SS-31 (elamipretide)?
Updated October 2026
SS-31 belongs to a small class of peptides that concentrate inside mitochondria — making it a key tool in bioenergetics research.
What it is
SS-31 (also known as elamipretide) is a synthetic tetrapeptide that associates with cardiolipin, a lipid found in the inner mitochondrial membrane. This targeting is the basis of most research interest in the compound.
Research directions
- Mitochondrial-membrane and cardiolipin-interaction studies
- Cellular bioenergetics and oxidative-stress models
- Comparative mitochondrial-peptide research alongside MOTS-c
