What is the difference between MOTS-c and Tesamorelin?
MOTS-c is a 16-residue mitochondrial-derived peptide encoded in the 12S rRNA region, described in 2015 and studied in cellular metabolism research (peptide, MW about 2174.6 g/mol).
Which is heavier, MOTS-c or Tesamorelin?
MOTS-c has a molecular weight of about 2174.6 g/mol and Tesamorelin about 5136 g/mol (PubChem), so Tesamorelin is heavier by 2,961.4 g/mol, a ratio of 2.36. This means 1 mg of MOTS-c contains 459.9 nmol versus 194.7 nmol for Tesamorelin.
How many mg of Tesamorelin are equimolar to 1 mg of MOTS-c?
1 mg of MOTS-c (MW 2174.6) is 459.9 nmol. The same number of moles of Tesamorelin (MW 5136) weighs 2.362 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of MOTS-c and Tesamorelin
PubChem lists MOTS-c as C101H152N28O22S2 (2174.6 g/mol) and Tesamorelin as C221H366N72O67S (5136 g/mol). MOTS-c is a peptide; Tesamorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
