Research context
MOTS-c is a mitochondrial-derived peptide of sixteen residues, with the molecular formula C101H152N28O22S2 and a molecular weight of 2174.62 g/mol. It is studied in metabolic and mitochondrial research as a synthetic reference compound and is supplied as a lyophilized, characterized material.
Supplied solely as a characterized research material. No representation is made as to any biological effect. For Research Use Only — not for human or veterinary use.
How MOTS-c is identified
Identity and purity are measured, not asserted. Electrospray mass spectrometry (ESI-MS) determines the mass-to-charge ratio of the intact molecule — an observed value matching the expected series above confirms the molecular formula. Reversed-phase HPLC separates the sample over time, and purity is read as arithmetic: the target peak’s area as a share of total peak area.
