What is the difference between Melanotan I and Vesugen?
Melanotan I is a linear 13-residue alpha-MSH analogue used in melanocortin-1 receptor research (peptide, MW about 1646.8 g/mol).
Which is heavier, Melanotan I or Vesugen?
Melanotan I has a molecular weight of about 1646.8 g/mol and Vesugen about 390.39 g/mol (PubChem), so Melanotan I is heavier by 1,256.4 g/mol, a ratio of 4.22. This means 1 mg of Melanotan I contains 607.2 nmol versus 2,561.5 nmol for Vesugen.
How many mg of Vesugen are equimolar to 1 mg of Melanotan I?
1 mg of Melanotan I (MW 1646.8) is 607.2 nmol. The same number of moles of Vesugen (MW 390.39) weighs 0.2371 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Melanotan I and Vesugen
PubChem lists Melanotan I as C78H111N21O19 (1646.8 g/mol) and Vesugen as C15H26N4O8 (390.39 g/mol). Melanotan I is a peptide; Vesugen is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Melanotan I equals how many mg of Vesugen in moles?
5 mg of Melanotan I (MW 1646.8) is 3.036 µmol. The same amount of Vesugen (MW 390.39) would weigh 1.185 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Melanotan I equals how many mg of Vesugen in moles?
10 mg of Melanotan I (MW 1646.8) is 6.072 µmol. The same amount of Vesugen (MW 390.39) would weigh 2.371 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vesugen equals how many mg of Melanotan I in moles?
20 mg of Vesugen (MW 390.39) is 51.231 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 84.367 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vesugen equals how many mg of Melanotan I in moles?
10 mg of Vesugen (MW 390.39) is 25.615 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 42.183 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
