Physical Properties
MOTS-c is a 16-amino-acid peptide encoded within mitochondrial DNA and synthesized as a short mitochondrial-derived peptide. Its compact structure supports aqueous solubility and practical handling under laboratory conditions. The peptide contains multiple basic residues contributing to overall positive charge at physiological pH. As with other short peptides, lyophilized storage and protection from moisture, light exposure, and repeated freeze–thaw cycles help preserve structural integrity and analytical consistency during research applications.

Frequently Asked Questions
What is MOTS-c?
MOTS-c is a 16-amino-acid peptide whose sequence is encoded in mitochondrial DNA. The synthetic material has the sequence Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg and is supplied as a white to off-white lyophilized powder.
Is MOTS-c a naturally occurring peptide?
Yes. MOTS-c is naturally encoded within mitochondrial DNA. Synthetic MOTS-c used in research replicates this endogenous peptide sequence for experimental investigation.
How does MOTS-c differ from traditional peptides?
Most peptides are encoded in nuclear DNA; the MOTS-c sequence is encoded in mitochondrial DNA. Chemically it is a linear 16-amino-acid peptide, supplied here in synthetic form.
How should lyophilized MOTS-c be stored?
Lyophilized MOTS-c should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
Does MOTS-c require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch of MOTS-c, verifying identity and purity to ensure research quality and traceability.
Is MOTS-c FDA-approved?
No. MOTS-c is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
