SS-31, also known as Elamipretide in clinical-development contexts, is a synthetic tetrapeptide studied primarily for its interactions with mitochondrial membranes and cellular energy processes. Its mitochondrial activity has made SS-31 an important research compound in laboratory investigations involving mitochondrial function, oxidative stress, cellular energetics, and metabolic signaling.

SS-31 research has explored its interaction with cardiolipin, a phospholipid concentrated within the inner mitochondrial membrane that plays an important role in mitochondrial structure and function. Researchers have examined how this interaction relates to electron transport chain activity, membrane stability, and the biochemical processes involved in cellular energy production.

Another significant area of SS-31 research involves reactive oxygen species and mitochondrial responses to cellular stress. Laboratory studies have investigated its relationship with oxidative signaling, mitochondrial integrity, ATP-related processes, and mechanisms associated with maintaining cellular homeostasis under experimental stress conditions.

SS-31 has a molecular weight of approximately 639.8 g/mol and is synthetically produced for research applications. This 25mg formulation is supplied in a nasal research format for laboratory investigation involving mitochondrial biology, cellular energetics, and oxidative signaling.
