SS-31

A mitochondria-targeting tetrapeptide examined in laboratory mitochondrial research.

SS-31, also known as elamipretide, is a synthetic tetrapeptide characterized by its affinity for the inner mitochondrial membrane lipid cardiolipin. In the published literature it appears predominantly in mitochondrial and cellular-bioenergetics research models. Describing it as "studied in" these areas reflects where scientific attention has gone, not a claim that it produces any effect. This content is background about the molecule as a research material and is not medical guidance or intended for human use.

Classification and structure

SS-31 is classified as a mitochondria-targeting tetrapeptide. Its alternating aromatic-cationic four-residue design gives it the cell-permeant, cardiolipin-associating properties that have made it a subject of mitochondrial research. It is handled in the laboratory as a defined peptide research compound.

Areas of research

SS-31 appears across several defined areas of the research literature.

• Mitochondrial research — Investigated in research examining cardiolipin interactions and inner-membrane organization.
• Bioenergetics models — Appears in the literature on cellular energy-metabolism research in vitro.
• Oxidative-stress research — Has been the subject of research examining redox parameters in model systems.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.
