1. What is SS-31?
SS-31, also known as Elamipretide, is a synthetic mitochondria-targeted tetrapeptide designed to support mitochondrial function. It selectively associates with cardiolipin, a phospholipid unique to the inner mitochondrial membrane, and has been studied for its ability to stabilize mitochondrial structure, reduce oxidative stress, and influence ATP production. Research interest has focused on its role in models of aging, mitochondrial biology, and organ function 【1】.
