What is the difference between MOTS-c and Melanotan I?
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 Melanotan I?
MOTS-c has a molecular weight of about 2174.6 g/mol and Melanotan I about 1646.8 g/mol (PubChem), so MOTS-c is heavier by 527.8 g/mol, a ratio of 1.32. This means 1 mg of MOTS-c contains 459.9 nmol versus 607.2 nmol for Melanotan I.
How many mg of Melanotan I 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 Melanotan I (MW 1646.8) weighs 0.7573 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of MOTS-c and Melanotan I
PubChem lists MOTS-c as C101H152N28O22S2 (2174.6 g/mol) and Melanotan I as C78H111N21O19 (1646.8 g/mol). MOTS-c is a peptide; Melanotan I is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of MOTS-c equals how many mg of Melanotan I in moles?
5 mg of MOTS-c (MW 2174.6) is 2.299 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 3.786 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of MOTS-c equals how many mg of Melanotan I in moles?
10 mg of MOTS-c (MW 2174.6) is 4.599 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 7.573 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of MOTS-c equals how many mg of Melanotan I in moles?
20 mg of MOTS-c (MW 2174.6) is 9.197 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 15.146 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of MOTS-c equals how many mg of Melanotan I in moles?
30 mg of MOTS-c (MW 2174.6) is 13.796 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 22.719 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
