SS-31 (elamipretide): the mitochondria-targeting peptide

SS-31, also called elamipretide, is a peptide studied for its localisation to mitochondria. This overview covers its structure and handling, with no therapeutic or dosing claims.

What it is

SS-31 is a short, mitochondria-targeting tetrapeptide. Its defining feature in research is that it concentrates at the inner mitochondrial membrane, making it a tool for studying mitochondrial function.

Why it is studied

SS-31 appears in preclinical and in-vitro mitochondrial and aging literature. The findings belong to those studies; nothing here is a statement about human effects.

Handling notes
