What MOTS-c is
MOTS-c is a mitochondrial-derived peptide encoded within mitochondrial DNA and studied in metabolism, stress responses and mitochondrial signalling.
What SS-31 / elamipretide is
SS-31, also known as elamipretide, is a mitochondria-targeting tetrapeptide with a distinct clinical-development history.
Mitochondrial-derived peptides
MOTS-c belongs to the mitochondrial-derived peptide field. SS-31 is mitochondrial-targeting rather than mitochondrial-encoded.
Cellular-energy and oxidative-stress research
MOTS-c research often concerns AMPK-related signalling and metabolic adaptation. SS-31 research often concerns mitochondrial membrane and oxidative-stress biology.
Differences between MOTS-c and SS-31
They differ in origin, sequence, mechanism and development status. They should not be treated as interchangeable.
Animal evidence
Animal evidence exists for both areas, but models and endpoints differ.
Human evidence
Human evidence for MOTS-c is emerging. Elamipretide has been studied in more formal clinical-development settings for specific conditions.
FAQs
Is SS-31 the same as MOTS-c?
No.
Are both mitochondrial peptides?
They are both mitochondrial-related peptide topics, but in different ways.
Scientific references
Scientific references should be checked against primary literature and review articles for the exact compound, model and endpoint being discussed. This article avoids converting cellular or animal findings into human efficacy claims.
