MOTS-c 5mg
Overview
MOTS-c is a mitochondrial-derived peptide (MDP) that has gained significant scientific interest for its potential role in metabolic regulation, energy balance, and cellular health. Composed of 16 amino acids and encoded within the 12S rRNA region of mitochondrial DNA (mtDNA), MOTS-c belongs to a unique class of peptides that act as messengers between mitochondria and the rest of the cell.
By influencing cellular metabolism, MOTS-c contributes to research exploring energy production, insulin sensitivity, and adaptive metabolism — offering insight into how cells manage energy utilisation and respond to metabolic stress.
The 5mg variant of MOTS-c provides researchers with a convenient format for controlled study environments where smaller experimental quantities are required.
Scientific Background
MOTS-c is one of several mitochondrial-derived peptides identified in recent decades, marking a new chapter in mitochondrial research. Unlike traditional peptides encoded by nuclear DNA, MOTS-c originates from mitochondrial genetic material, enabling it to play a direct role in mitochondrial-to-nuclear communication (retrograde signalling).
Through this mechanism, MOTS-c is believed to help regulate cellular energy homeostasis, metabolic adaptation, and oxidative balance, making it a focal point in studies of metabolic disorders, ageing, and cellular stress responses.
Mechanism of Action
Research indicates that MOTS-c functions primarily through activation of the AMP-activated protein kinase (AMPK) pathway, a master regulator of energy metabolism.
By stimulating AMPK and related signalling cascades, MOTS-c may help:
-
Enhance glucose uptake and utilisation in muscle cells
-
Increase fatty acid oxidation
-
Promote mitochondrial biogenesis and efficiency
-
Improve cellular resilience under metabolic stress
These effects position MOTS-c as an intriguing research target for exploring energy regulation and metabolic flexibility at the molecular level.
