They are encoded in mitochondrial DNA rather than nuclear DNA, and they function as signals from mitochondria to the rest of the cell. Their discovery changed how scientists view mitochondria — from passive energy generators to active signaling organelles.

AMPK is the cell's master energy sensor. When activated (by exercise, caloric restriction, or compounds like MOTS-C), it triggers metabolic adaptations including increased glucose uptake and fat oxidation. MOTS-C is studied as a potential AMPK activator.

MOTS-C activates some of the same pathways as exercise (notably AMPK), which is why it's sometimes described as an "exercise mimetic" in research. This does not mean it replaces exercise — it means it's a useful research tool for studying exercise-related metabolic pathways.

Both are studied in aging and metabolism, but through different mechanisms. NAD+ works through sirtuin activation and electron transport chain function. MOTS-C works through AMPK activation and mitochondria-to-nucleus signaling. They represent different approaches to studying cellular metabolism.

Store lyophilized MOTS-C at -20°C for long-term or 2-8°C for short-term. Protect from light and repeated freeze-thaw cycles.

Every batch is independently tested via HPLC and LC-MS. The COA is downloadable on this page.

MOTS-C was first described in 2015 by Dr. Changhan David Lee's laboratory at USC. It is one of the newest peptides in active research.
