About SS31

SS-31 (Elamipretide) is a synthetic tetrapeptide that selectively targets the inner mitochondrial membrane. In research settings, it is used to study the stabilization of cardiolipin and the optimization of the mitochondrial electron transport chain. Laboratory investigations focus on its capacity to reduce the production of reactive oxygen species (ROS) and maintain mitochondrial bioenergetics under conditions of cellular stress.

Molecular formulaC₃₆H₅₃N₉O₅
