What is the difference between Melanotan I and Vilon?
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 Vilon?
Melanotan I has a molecular weight of about 1646.8 g/mol and Vilon about 275.3 g/mol (PubChem), so Melanotan I is heavier by 1,371.5 g/mol, a ratio of 5.98. This means 1 mg of Melanotan I contains 607.2 nmol versus 3,632.4 nmol for Vilon.
How many mg of Vilon 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 Vilon (MW 275.3) weighs 0.1672 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Melanotan I and Vilon
PubChem lists Melanotan I as C78H111N21O19 (1646.8 g/mol) and Vilon as C11H21N3O5 (275.3 g/mol). Melanotan I is a peptide; Vilon is a dipeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Melanotan I equals how many mg of Vilon in moles?
5 mg of Melanotan I (MW 1646.8) is 3.036 µmol. The same amount of Vilon (MW 275.3) would weigh 0.8359 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 Vilon in moles?
10 mg of Melanotan I (MW 1646.8) is 6.072 µmol. The same amount of Vilon (MW 275.3) would weigh 1.672 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vilon equals how many mg of Melanotan I in moles?
10 mg of Vilon (MW 275.3) is 36.324 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 59.818 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vilon equals how many mg of Melanotan I in moles?
20 mg of Vilon (MW 275.3) is 72.648 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 119.6 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
